Washington (ECN) - Today marked the day that the Rhapsody MP3 music store launched, proving to be the latest and greatest challenger to try and dethrone the Apple iTunes service.

Rhapsody MP3 will be offering songs which cost $0.99, and albums costing $9.99.

One of the biggest selling points of the RealNetworks' Rhapsody MP3 music store is that all of the music you purchase will be completely DRM-free.

This means that you will be able to take any music you purchase off of the store and play it on any device, including an Apple iPod.

Rhapsody will even have an option to download a small app to automatically add new songs to iTunes.

The new music store appears poised to make quite a splash.
