"MY WORLD in 5 days...please spread the word and try and wait and support the music when it comes out," Justin Bieber tweeted today. "We all worked really hard 4 this. :)"

Yes, the countdown to the release of the 15-year-old sensation's debut album, 'My World,' is on, and the Canadian singer is kicking things into high gear. Justin recently stopped by MTV to record a few acoustic songs, including 'One Less Lonely Girl' and a chill version of 'Never Let You Go,' and talks about his musical beginnings as a drummer.

Pretty cool, right?
