AT&T Mobility is responding to the dip in ringtone sales and the sluggish pace of full-song downloads by offering a pair of new services that allow subscribers to access and customize their music libraries.

Addressing the ringtone issue, AT&T introduced Make-UR-Tones, a service that lets customers create customized ringtones from their mobile phone. Songs available include more than 250,000 tracks from all major labels save Sony BMG, and independent labels/distributors INgrooves and IRIS Distribution. It's available on three Samsung music phone models and the Motorola V3xx.

Next up is the Remix service, which lets customers download their PC-based music library to mobile phones without having to repurchase any songs. Each song can be played in full while the download takes place, and the user's PC need not be on to access the music. The Remix service is compatible with several Samsung music phones and the LG Shine.

Putting a damper on both developments, however, is the pricing. The ringtone service costs $7 a month for the ability to make three ringtones. Additional tones cost $3 on an a la carte basis. There is no option for someone who just wants to create a one-off custom ringtone and be done with it.

The Remix service costs another $10 a month for access to 75 songs a month, with a "booster pack" adding an additional 10 songs a month for $3 extra. So that's $10 a month for the privilege of accessing music you already own over the air when you can just sideload to your phone for free when connected to a computer.
Additionally, AT&T says it will add support for the Napster Mobile application to additional phones this summer. The service launched last November on only the Samsung SLM. The company did not specify which or how many models.
