This has been discussed here before, but not for while and nothing has changed.
XM has no AAA channel.
The cafe and loft are too similar and do not mix in enough rock. They both seem to be aimed specifically at women - in my mind, women at the Starbucks or Barnes and Noble Cafe reading Wurhering Heights - but that's just me.
There is simply nothing like the AAAs of FM that I am familiar with including KSCA and Channel 103.1 here in LA (and KMPC-FM/KEDG-FM, the pioneer of what would become the format), KFOG in SF and the station in Boston, I believe called the River (been awhile since I listened to that one, so I may have the name wrong).
