Nicole is not on the radio, first because she did not sell out, and second because she does not talk about stupid shit and ignorant behavior like most pop, hip hop and r&b on the radio! If you don't brag about what you have, talk about what you want to have, or sing about things that are demonic and lead to harm to others or yourself, then you will not be successful today in the music industry! It's sad but it's true!

Example
Rapper: "I just fucked your bitch in my new bugatti"

Listener: "Yeah! That's the best thing ever! That's a hit!"

Singer: "I just wanna give my love to you, spend time with you, let me prey with ya, spend all day with ya, for once can I just keep it real?"

Listener: "lame lame lame! That is soooo lame! That ain't a hit!"

That's how music works today, just listen to what is popular and what isn't.

Rihanna, Nicki Minaj talk about stupid shit and are played all the time.

Nicole and Johnny Gill talk about love and life, they have real music actually about something than just selfishness, but yet they get no love in the mainstream. It's sad.
