Canadian online music store, Puretracks, has announced Puretracks Mobile Edition for the BlackBerry. Puretracks Mobile Edition runs on the BlackBerry Pearl, BlackBerry Curve, and BlackBerry 8800 series devices.

Puretracks Mobile Edition is designed specifically for mobile handsets and thus music downloads are a compressed DRM free AAC/AAC+ format that are about half the size of traditional MP3s. You undoubtedly will sacrifice a bit of audio quality because of the decreased file size, however, the Purtracks Mobile Edition press release states that CD quality sound is maintained.

Puretracks Mobile Edition for BlackBerry will officially be available after April 1st when it is launched at CITA Wireless. You can, however, get a sneak about March 12th at the South By Southwest (SXSW) event being held in Austin Texas.
