XM Satellite Radio and AOL have teamed up to add XM satellite feeds to AOL's Radio@AOL internet radio service. Users will be able to access 20 XM channels on AOL's radio section, in addition to AOL's current lineup of about 130 stations - for free.
A new version of AOL's "premium" radio service will have 70 XM channels and be available for a monthly fee at a rumored $5/month.
AOL will own the task of building the radio service which is probably will the current Radio@AOL infrastructure based on Ultravox and the AACPlus streaming audio format. AOL expects to begin rolling out the new internet radio service with XM streams this summer, in conjunction with the new AOL.com portal.
Yes, there will be commercials on the AOL channels, but the XM channels will remain ad-free.
XM also plans to replace its current XM Radio Online service (which now is free to subscribers as of last week) with this new AOL-powered service when it launches this summer.

In the spirit of Satellite Radio, I will not edit or remove any comments unless they are purely promotional. The
"seven forbidden words are completely acceptable"
(Those seven forbidden words really shouldnt be used or recomended but then you go and promote them?)
"so go nuts"
how are you being in the "spirit of Satellite Radio" by promoting bad language? XM and Sirius never (As far as i have heard) use the seven forbidden words!
Just my 2.2 Cents worth
