Like Apple's iTunes Music Store, the Sony service will charge $ 1 per song and have a library of around 500,000 songs. It will also be designed to integrate with Sony's portable players, possibly including those using the new 1GB MiniDisc format.

Support for other, non-Sony players is expected to be provided at a later date. Apples iTMS, on the other hand, is only compatible with iPods, as the company says that iPod sales are the only way it can make money from the store.
