'Rock Your Body'
According to Billboard, the Justified singer wasn't the first choice to perform the song. Super music producers The Neptunes had sent the track to the late Michael Jackson first, but he passed on the song along with a number of other hits on J.T.'s first solo record.
'Whataya Want From Me'
This song was thought to show up on Pink's Funhouse album, but later became Adam Lambert's most successful song to date. Pink, however, did record Whataya Want From Me and placed it on her 2010 compilation Greatest Hits… So Far!!!
'Don't Cha'
The Pussycat Dolls' first hit in 2005 titled Don't Cha was first offered to the Sugababes and Paris Hilton.
'How Will I Know'
Before the late Whitney Houston made How Will I Know a Hot 100 hit, Janet Jackson was offered the track.
'S.O.S.'
Christina Milian turned down the chance to sing S.O.S., which, as it turns out, was the track that catapulted Rihanna to super-stardom in 2006.
'Let's Get Loud'
Gloria Estefan originally wrote Let's Get Loud for herself alongside Kike Santander, but ended up giving it to Jennifer Lopez who turned it into a 1999 hit.
'Since U Been Gone'
Before Kelly Clarkson made Since U Been Gone the ultimate breakup anthem, Dr. Luke and Max Martin first offered the track to both Pink and Hilary Duff.
'Disturbia'
Chris Brown co-penned Disturbia, but decided to pass it along to his then girlfriend Rihanna who turned it into a No. 1 hit.
'Telephone'
Lady Gaga reportedly wrote Telephone for Britney Spears' album Circus. In 2010, an alleged rough cut of Spears singing the song was leaked, but that's the closest we've ever gotten to hearing Spears' rendition.
