    Slay Katy yassssss.

    • miao October 1, 2013

      It was OK. Basic generic Martin/Dr Luke songs, basic dance routines, basic vocals, basic look. 30 y.o. woman acting/dancing like she’s 13. But, still it was OK.

    • miao October 1, 2013

      And her Dark Horse dance.. damn.. LOL!

  2. Super Cisus October 1, 2013

    • Lovebird (Prism – 10.22.13) October 1, 2013

        Rihanna doesn’t need to seat front row, she gets to showcase her own collection at fashion week.

    • Slayty Perry (By The Grace Of God) October 1, 2013

      • Lovebird (Prism – 10.22.13) October 1, 2013

      • cake like lady gaga October 1, 2013

      • Lovebird (Prism – 10.22.13) October 1, 2013

    • Lovebird (Prism – 10.22.13) October 1, 2013

      If it’s sucking d*** to stop FLOPause from free falling off the charts, I’ll pass. I’ll leave that for you monsters.

      • cake like lady gaga October 1, 2013

        Lame a** comments from a lame a** d*** who has no job and living off his fathers welfare. You been saying the same thing for weeks now.

        I don’t know what you consider “free falling” since Applause is still in the top ten..

      • Lovebird (Prism – 10.22.13) October 1, 2013

        Is that so, your d*** sucking lips must be paying off then.

      • Slayty Perry (By The Grace Of God) October 1, 2013

        B**** you’re the lamest one on TGJ with your pedestrian shade.

    • POP ROYALTY October 1, 2013

  12. New Life/Queen Monica October 1, 2013

    by the grace of God, as she wears a fish net outfit showing all her body. This world is so confused. Kiss a girl and then sing about the grace of God. Have several in the hot sun

    • Slayty Perry (By The Grace Of God) October 1, 2013

      Did you actually listen to the song? It’s really not spiritual. And I can’t with you complaining about religious values and judging Katy. You must be confused. I’m pretty sure God is the only one who can judge her. Have a seat in the hot sun and read the Bible so you don’t look like a fool

      • New Life/Queen Monica October 1, 2013

        y don’t both of you go and listen to what her father (a preacher) said about her mnusic. I haven’t judged her one time. I like her music actually, I was just a bit confused by the title, and what she was wearing when she sang it. so calm down and don’t get so b*** hurt about my comments towards these satanic devil worshipers. U sell your soul, you sell your soul. So why u sit here and ponder what I’ve said, let go of her c***, and get on youtrube and look up what she said about selling her soul to make money and fool the sheep (YOU).

    • Perry Power October 1, 2013

      The amount of irony in this comment…..

  13. Slayty Perry (By The Grace Of God) October 1, 2013

    Katy gave me all sorts of life with By The Grace of God!! Yes yes yes yes yes!! I can tell it will be one of my favorites. Her vocals and outfit were on point! Much better than iHeartRadio set. Btw, Walking On Air went to #1 on iTunes (Which is why she performed a new single). How can Katy go to #1 with a promo single by simply tweeting about it. That Charty Perry reign.

  14. Twerk 4 Miley October 1, 2013

    By the grace of god>>>>> anything GaGa has released.

  15. Perry Power October 1, 2013

    Walking on Air and By the Grace of God were my favorite performances of the night! I loved the WOA choreography the most. Katy has never been a dancer but she’s getting much better at it. By the Grace of God really moved me though. The lyrics are so honest and raw and she sounded amazing. My favorite part was when she gave her sister Angela a shout out. Her sister has helped her throughout her career and has always been there for Katy. That was sweet of her

    • Twerk 4 Miley October 1, 2013

      Her dancing was good & the vocals were on point… ill be buying prism

  16. POP ROYALTY October 1, 2013

    I love how she promotes herself WHILE she actually promote herself… Business 101. 😆

    and how she didn’t reveal so much tracks from her upcoming album… marketing genius …. never show all of your cards at once. 😉

    she has major problem in breathing while performing , other than that, I’m cool.

    Liked “WOA” the most so far.

    I’m buying “PRISM” when it is available here.

  17. Scheissethroned(GrapejuiceKing) October 1, 2013

    @IRRELEVANCE B**** stfu she revealed over 4 songs which is about the same amount as Gaga did! The only difference is she released the studo versions! Gaga just performed them differently than the studio versions so we still don’t know what it’ll sound like!

    AND BTW GAGA DID THIS ALREADY FOR HER BTW ERA SO SIT!

    Anyways… Katy not bad. Not good. But not bad

  18. JOHNVIDAL October 1, 2013

    This is a girl at the peak of her career and youth and getting all the possible media support right? She is also a pure pop artist, you know the ones who are supposed to bring something knew and give spectacle, not some good vocals or music but something else right? Well let me explain what it feels like for a common person watching her:
    She really can´t sing at all. She can´t dance or put on a show either. This is getting to a point where even some Rihanna´s live performances are better than most of these young girls (very few, only some Diamonds and Stay here and there and that´s it). It´s truly sad. The only parts where she sounded kind of good were the backing-tracks. Musically nothing new or at least dark or interesting or something. Total basic fail.

    • Perry Power October 1, 2013

      I cannot with you trying to pass yourself as an unbiased casual listener when you hate on Katy in damn near all of your comments. You said she was at her peak during the Teenage Dream era and here she is outdoing that. Katy doesn’t qualify as a pure pop artist when she crosses into adult contemporary with alot of her songs, especially off her debut album. Pop stars are supposed to entertain, and according to the general public, she does it well. The California Dreams Tour sold out over 98% of it’s dates. If she was boring no one would pay to see her. Her dancing has improved and she definitely can sing as seen in several of the performances posted above. No one in pop is doing something new, it has all been done before. She is doing something different. With everyone doing EDM, Roar was refreshing to hear on radio. And since when did dark=interesting? What pop star hasn’t gone the “dark” route? To me that’s basic and predictable. Katy stays true to herself, something no other pop star has done.

      Side note: This post is full of irony when you support Lady Gaga and Lana Del Rey, both average singers who cant dance and bring nothing new to music.

      • Stop the drama Start the music October 1, 2013

        Actually Gaga’s voice is much stronger than Katy’s. Katy is a studio singer with pitch problems.

      • JOHNVIDAL October 1, 2013

        Like this @stopthedrama sane person already said Lady Gaga can sing way better than Katy, way way better, she has vibrato and controls her voice perfectly. Lana is really bad at live performances just like Katy, but her voice is magical in her recordings, which is what she´s talented for: creating haunting music. Those two ladies are way better artists than Katy.
        The fact you really think Katy brings something new to music but Gaga or Lana don´t is hilarious and just a proof of how laughable your opinion is, similar to that other joke called @lovebird. You people can keep stanning for Katy, Rihanna, Justin Beiber and the rest. It says it all.
        Next thing you´ll say is Katy dances better than Gaga LOL
        And btw I didn´t mean at the peak of her career commercially, maybe my English is not good enough. I meant to say she is in top form, her vocals (hilarious to talk about her as a vocalist) are the same, she´s young, etc, etc. Some people who really work hard start losing some of their abilities as a result of work and age (normally true greats who are really special and actually posess something they can lose). I meant to say Katy is at “her best” since she has not suffered any type of decline. The fact she is this bad with all her “talents” in form is a disaster.

  19. Unapologetic October 1, 2013

    Wow she has slayed so hard this era. I mean i am not her biggest fan but 3 song in the top ten on itunes and two of them are in the top 2 and they are just promotional singels without any videos.Say what you want but she did it.

  20. Stop the drama Start the music October 1, 2013

    Who is this Betty Paige reject??

  21. FLOP THIS WAY October 1, 2013

    ANOTHER GENERIC TRACK

    HER PERFORMANCES PER USUAL BASIC WITH MEDIOCRITY!

    MORE BASIC SONGS THE MUSIC LISTENERS OF THE MODERN TIME WILL EAT UP AND LOVE.
