Sirius has a great indie station, Left of Center. It is what I pay the monthly fee for. At night they have various bloggers come on and play new stuff. It comes across a lot better then what I'm desribing, but it is a great way to listen to stuff before it is released or even hyped by major sites like Pitchfork.
The Alt Nation channel sucks and I don't blame you for judging Sirius based upon that.
Check out Left of Center when the merger goes through.
