Everyone seems to be getting into the music retail industry, but so far, Apple has been the only one to have had considerable success. With the likes of Nokia, Sony Ericsson, and Amazon via Android just waiting to go full throttle with their own music service, competition definitely isn’t lagging far behind.

However, in the case of Sprint’s Music Store, it seems that things aren’t headed towards a brighter tomorrow. Sprint has announced that starting October 15, tracks purchased from their Music Store can only be played on a phone. You can still back it up on a PC for safe-keeping, but it can’t be played back on it. I wonder how long Sprint can make a profit out of this enormously restrictive environment when others offer the same type of service without that many limitations.

Anyway, just take this bit of news as a warning so that you won’t be surprised once its implemented on October 15.
