Get Britney. According to last weeks Billboard charts, she's managed to get a US hit single with a song that hasn't even been released. 'Do Somethin' made it to number 100 based on airplay alone, and has had no official release and no specific promotion.
The track, which made it to number 6 in the UK, was one of two new songs which were included last year on Britney's Greatest Hits set. US stations began playing it in response to repeated requests by the singer's fans.
