What a coup for Amazon.com! Warner has decided to make it’s entire music catalog DRM-free through Amazon’s MP3 store.

The best part? It’s going to be DRM-free! This deal boosts Amazon’s MP3 offerings to 2.9 million songs.

Walmart on the other hand has quit the video download industry. It’s clear that they’re not able to dominate this super competitive industry. This leaves Amazon’s Unbox as a dominant player.
