Warner isn’t the first major label to enter the eMusic fold. Sony Music signed on last year to provide catalog recordings on the subscription service.

The deal covers recordings from Warner Brothers, Atlantic and Rhino as well as indie imprints distributed by the label.

“As a leader in the music industry’s transition to a predominantly digital music business, we have worked hard to encourage and support innovative partners and creative business models that offer our artists unique ways to reach their fans,” said Stephen Bryan, WMG Senior VP of digital strategy and business development. “We are pleased to be making our music available to eMusic’s passionate membership.’

eMusic’s business plan is simple. Customers pay a monthly subscription fee for downloading a predetermined number of tracks. The higher the subscription rate, the more monthly downloads. Since all tracks are ripped as MP3s and are not copy-protected, music downloaded from eMusic will play on any device.

Evidently, eMusic began loading up on WMG product almost as soon as the ink dried on the contract. A quick perusal of the service’s forums shows fans remarking about the new additions, such as a Paul Simon box set, Ramones CDs and the recent Flaming Lips release.

Or, as one customer wrote:

“I know we’re not supposed to like major labels, but screw it. This is AWESOME!”
