This is huge:

After a decade fighting to stop illegal file-sharing, the music industry will give fans today what they have always wanted: an unlimited supply of free and legal songs.

With CD sales in free fall and legal downloads yet to fill the gap, the music industry has reluctantly embraced the file-sharing technology that threatened to destroy it. Qtrax, a digital service announced today, promises a catalogue of more than 25 million songs that users can download to keep, free and with no limit on the number of tracks…

Qtrax files contain Digital Rights Management software, allowing the company to see how many times a song has been downloaded and played. Artists, record companies and publishers will be paid in proportion to the popularity of their music, while also taking a cut of advertising revenues.

Sweet.
