AT&T Inc. (NYSE:T) has announced the launch of an over-the-air music download service with eMusic, the world’s largest retailer of independent music. The eMusic over-the-air (OTA) service will give AT&T’s customers the ability to preview and purchase music via their wireless devices from a catalog of 2.7 million songs, the nation’s largest wireless music catalog. This new service is part of the AT&T Mobile Music platform, which provides customers with more music choices than any other wireless carrier.

Songs purchased from eMusic Mobile are immediately sent to the user’s wireless handset, and a duplicate copy is available for download to the user’s PC at no charge. AT&T customers can subscribe to download five tracks a month for $7.49, and additional packages of five songs are available for the same price whenever desired.

“eMusic Mobile is not your typical over-the-air service,” said Mark Collins, vice president of Consumer Data Services for AT&T’s wireless unit. “This service, which is as unique as the independent artists found in the eMusic catalog, differentiates itself from the competition through its ease of use, subscription pricing model and the ability to play these tracks in any MP3 player.”

“eMusic Mobile will expand the audience for mobile music beyond the youth market by offering an alternative to the mainstream pop hits that have so far dominated over-the-air music,” said David Pakman, eMusic president and CEO. “AT&T is a terrific partner for this service, and we look forward to offering AT&T’s more than 63.7 million subscribers access to a rich catalogue that ranges from legends like Paul McCartney and Miles Davis to new independent stars such as Spoon and Arcade Fire.”

eMusic Mobile will prove to be a valuable tool for music discovery when users are on the go, hear a song on the radio or in a store, and want to hear it again. The service allows for the preview of tracks before purchase and is perfect for making sure that same great song is the right one before purchase.
