Hurt is doing fine in MN has of right now...so I wouldn't say it's a flop. Yeah it's true they don't ***** it up on the radio like JT and Akon but it still get's played at least 5 times a day. But now it's losing it's grip and they aren't playing it so much now. It could've been a bigger hit though.
Kelis pretty much flopped ever since Bossy died down. Blindfold me was never even played from what I know of.
Rihanna well radios here skipped We Ride and went straight to Break it Off and that's doing pretty decent of right now.
Jojo hasn't been picked up at all with her new single. TLTL is still being played once in a while each day but H2TAG isn't really radio single worthy! It probably won't pick up at all with the success she's having lately
Danity Kane isn't doing much here either. At least that I don't know off. They used to play ShowStopper once in a while each day but Ride for You isn't picking up yet.
And last not but least....Cherish. They are doing perfectly fine

They play Do It To It and Unappreciated but not *****d up like some other artists

They released a good 2nd single because it actually picked up here.
Yipee that is my speech for every new single!!
