Unreleased Britney Spears Track Becomes Instant Hit  4/9/05

Pop beauty Britney Spears is stunned her latest song Do Somethin' has become an instant US hit - because she hasn't even released it yet.

The TOXIC beauty's ballad entered the Billboard chart at number 100 this week (begs04APR05), despite the fact her label Jive Records has not officially released or promoted the song.

Instead, the 23-year-old has her fans to thank for the unexpected hit, because they heard the single on last year's (04) Greatest Hits: My Perogrative album and swamped American radio stations with so many requests for it, the song made the chart based on airplay alone.
