Wireless operator AT&T is revamping its entire mobile music offerings by merging several new and existing services into a single application called AT&T Music.

The move combines applications like Music ID, streaming radio services, lyrics search, full-song downloads, and music management software into one app. Most are applications that have been available for years, but as separate applications, meaning users had to use each app one at a time and there was no interaction between them.

The Music ID app for instance launched in March of 2006, and since then has registered more than 36 million identified songs. The operator also has offered such streaming radio services as XM Radio, Pandora and MobiRadio for years.

Until now, all of AT&T's music services have been provided by other partners. With the AT&T Music App, the operator will now offer its own branded services -specifically the AT&T Radio service and a new music download store. AT&T has deals with Sony Music, EMI Music and the Orchard for the download store, and is in negotiations with other labels to complete its catalog. Until now, AT&T customers could only buy music through mobile download services from eMusic and Napster.

Interestingly, the AT&T Music app does not include ringtones or ringback tones, which presumably will continue to be available through separate applications. AT&T says it will add support for ringtones and ringback tones in the coming months.

The app is provided as a monthly service for $7 a month, and requires a data plan as well. At launch, it's available only on three phones-the LG Xenon, Samsung Solstice and Samsung Impression. The company says it will extend the service to additional devices soon, and will preload the app into even more devices by this summer.

Labels have been pushing mobile operators to offer this kind of integrated experience for years, but have found them to move very slowly on this point. For instance the ability to ID a song from the phone and within the same app choose to buy the full song, ringtone, or ringback tone. The primary reason for this is that operators work with different partners for each capability, making it difficult to impossible to merge them into a unified experience.

Verizon Wireless has done this for the last few years after centralizing all its music services under one provider-RealNetworks-which includes full song downloads from the Rhapsody service. In February, Sprint entered into a similar deal with RealNetworks for a unified music storefront for ringtones, ringback tones and other services.
