I didn't realise that Timbaland released this seven-track ringtone-only album earlier this year, which obviously you can download for free (the site has 30 second samples, which is the whole track). I read about it in this NY Times feature (click here for a password if you're not registered), which also mentions, but fails to properly explain, the concept of a "Ringtone DJ". More Timbaland. (Thanks, Tristan)
