AT&T launching music phone

The device, called the trax by LG, features AT&T Mobile Music and gives users access to subscription music services such as Napster and eMusic.

It is also MobiTV and XM Radio Mobile-capable so users can access streaming live TV and digital radio on their device. Emeryville-based MobiTV provides television and music content for mobile devices and broadband, and partners with AT&T on packages.

The trax also can be used to access AT&T's Cellular Video (CV) service, which features content from CNN, the Weather Channel, Comedy Central and HBO.
