XM Satellite Radio has confirmed the reports that they are teaming up with Cingular to provide a limited number of XM music channels to Cingular subscribers.

Starting on November 6th, Cingular customers will be able to listen to XM Radio Mobile, XM's new mobile service providing 25 XM channels, for $8.99 a month. 

Channels will be browseable by genre, including The 70s, 80s and 90s decades channels, Top
20 on 20 (Top 20 Hits), Lucy (Classic Alternative Hits), The City (Hip-Hop/R&B Hits), XMU (Indie Rock), Bluesville (Blues), America (Classic Country Hits), and Viva (Latin Pop Hits). A full list of the 25 channels is supposedly available on Cingular's website, but I can't find it yet. UPDATE: Cingular will have more info on their website when the service launches on November 6th. A full list of the channels is available after the jump.

XM will also provide the "PAD data" that will let users see the song title, artist and album while listening on their handset. The XM Radio Mobile application was developed by MobiTV.

Earlier today the Wall Street Journal wrote that Cingular was planning on announcing a partnership with Napster and Yahoo! Music to launch a cellphone music service. The announcement is set to occur tomorrow.

Now Reuters is reporting that Cingular is raising the bar (sorry) and including XM's Web-based channels as part of the offering.

Billboard further elaborates, reporting that the XM service (XM Radio Mobile) will provide 25 music channels. XM Radio Mobile on Alltel currently consists of 20 channels, no word on whether the service is being expanded on both mobile providers.

According to the WSJ, Cingular's service will allow for the transfering of music from "all you can eat" subscription services like Napster to Go, Yahoo's Music Unlimited or eMusic. Next year, Cingular will add over-the-air downloading with a virtual store menu, similar to the one customers already use to buy ringtones.

Some speculation: remember that back in April, Cingular said that they are in talks with a new satellite video provider, one who is not Dish or DirecTV. Not sure if this is related, but the timing is curious.

Some thoughts: it's step forward to the ultimate goal of "device convergence" - but not quite there yet. Hopefully it's a taste of things to come.
