There’s a new music store coming from Puretracks on April 1st. called Puretracks Mobile Edition, which will offer 64kbs AAC music without any DRM whatsoever. The AAC format they’re using gets roughly twice the quality at half the size of MP3, so the music will be approximately the equivalent of a 128kbs MP3. Not enough for audiophiles, perhaps, but probably good enough for the rest of us. There’s no indication of pricing yet, but they did say they’ll be releasing Wi-Fi capability for the service later on.
