Warner Music Group agreed to sell its entire catalog of DRM-free (unprotected) tunes on Amazon.com Inc.’s digital music store last Thursday. This catalog includes the work of Led Zeppelin, Aretha Franklin and Sean Paul. This will result to the raise of available mp3s on the Amazon Digital Music to 2.9 million.

It was previously known that Warner Music had resisted selling songs by its artists in the MP3 Format, which can be copied to computers, compact discs, digital media players like the Apple iPod and the Microsoft Zune.

The Universal Music Group, EMI Music Group PLC together with thousands of independent music labels previously signed to sell huge portions of their catalog on the Amazon Digital Music Store.

Most of the songs being sold on the Amazon Digital Music Store are priced from 89 cents to 99 cents while most albums / music compilations are sold from $5.99 to $9.99.
