Veteran online music store eMusic today said it has registered its 250 millionth download since its subscription service began in 2003. The company is one of the few outside of Apple to reach the milestone and is owed partly to eMusic's business model, which offers unprotected MP3s compatible with Apple and Microsoft players but uses a subscription model which guarantees a certain number of songs at rates that typically fall well below the 99 cents per track found at iTunes and other stores. An entry $12 monthly plan gives users 30 downloads per month, or about 40 cents per song.
