Cingular Wireless has agreed to team up with XM Satellite Radio and Napster, Yahoo and others, to let its customers play songs on their cell phones. Beginning Nov. 6, Cingular Wireless customers will be able listen to a variety of XM's popular commercial-free music channels through the XM Radio Mobile service.

Cingular is the first U.S. carrier to distribute subscription music to the handset - allowing consumers to extend their existing music libraries not rebuild them. Highlights include:

- Napster: For a monthly subscription price of $14.95 a month, Cingular customers can fill and refill their phone by connecting their phone to their PC and downloading tracks from among Napster's more than 2 million songs. For $0.99, consumers can also buy songs on the handset for delivery to the PC for side-loading later.

- Yahoo! Music: With Yahoo! Music Unlimited To Go, Cingular customers have unlimited access to over 2 million songs to play and transfer from their PC to their mobile device (rates are as low as $11.99 a month). With Yahoo! Music for Mobile, Cingular customers can, on their mobile handsets, browse the extensive Yahoo! Music catalog for album, artist and song content as well as receive personalized music recommendations and remotely add songs direct to their PC.

- eMusic: Currently, consumers who purchase a Sony Ericsson W810i or Sony Ericsson W300i will be able to enjoy a free "in-box" offer to side-load up to 50 songs from eMusic's catalog of two million tracks. Not only can consumers transfer eMusic's MP3 tracks to multiple devices and burn them to CD, they also own, not rent, tracks purchased from eMusic.

Cingular also teamed with XM Satellite Radio to offer mobile access to audio streams of 25 popular commercial-free music channels. Through XM Radio Mobile, Cingular customers will be able to enjoy a variety of music for $8.99 a month.
