Let me first say I am a huge huge Janet fan and have been for many many years, Ive been to two of her concerts and most recentley I saw her on her Number Ones Tour. But what you guys have to realize and if you dont believe me you can watch the videos on youtube... everytime janet does a new tour, she picks her setlist and goes into the studio to record the new vocals for the tracks, so when you see a new tour pop up you are hearing a new janet because she recentley recorded those vocals. When she did the rockwitchu tour she (as she did with tours before) she went into the studio and recorded the new setlist. The Rockwitchu tour only had 16 shows, so this number ones tour still uses the rock witchu tour vocals that she recorded. Every single song in this number ones tour is pre-recorded to sound live, as she goes on her tour. I'll give her the benefit of the doubt and say that she possinley sings the slower songs. But there is no way, when she has the headset mic on that she is singing one note. Dont believe me? GO ON YOUTUBE and check out If from Toronto, then If from Barcelona its the SAME VOCALS IT DOESNT MATTER WHAT CITY, every song uses the same vocals, the same 'Ows" and the "oos' and 'one-hundered DIFFERENT wayyyys" in the song if, and the everything it is NOT LIVE!!!!!!!!!!!!!!!!!!!!!! I love Janet to death but I am not that stupid, honestly. But I will give it up to her that she does a great job at playing that part and she lip syncs very well. Even when she does scream on this tour, compare it to the 2009 vma it is THE SAME TRACK with the same riffs and note arrangment in every single city... if she was singing it you would think that city to city it would sound a bit different but no its identical look on youtube. And even when she talks (cause her headset mic is on) she will say "come on!!!" or whatever in such a raspy voice 2 seconds later shes singing perfectley with clear crispy sound its NOT LIVE, im sorry. Still dont believe me check it out on Youtube and compare the cities to see if they sound different they dont there the same tracks being played again and again.
