One question
why is the sound quality only 31kbps? Shouldn't be much better quality?

I believe Sirius internet radio streams different quality of feeds, based on a few situations.
If you sign up for the free trial, Sirius does not stream the higher quality (128kbps, or what they call CD Quality) feed to you. The free trial feed, is also the lower quality feed you get if you already have a Sirius Radio that you pay monthly dues for, but not the monthly dues for an Sirius internet account.
You have to sign up for the Premium Internet service for the high quality 128kbps feed (2.99/month if you already have a current radio account, or $12.99/month if you have no radio account).
Even with this, I've noticed (and remember reading somewhere) that Sirius (and XM) send different quality feeds (whether it is an internet account, or to a standard radio account) based on the signal demand and popularity for that particular station. A voice only channel (like Comedy channel) will get a lower quality feed, as it doesn't need the full stream to sound good. Also, some of the channels don't get the number of listeners, so they use lower quality streams (like the Jazz stations I've noticed). They do this to save satellite bandwidth, but it's also the quality sent via the internet streams (just a copy of what's sent out the antenna).
So far while using the uSirius player, I've seen 31k, 48k, and 128k streams. I'm a premium subscriber, and did check the uSirius toggle for the higher quality feed.
31k is almost 'junk' IMO. So many compression artifacts that it's hard to listen to. 48k is ok, but it's still a bit noticeable. 128k is awesome. It does work on an edge connection.
I did an hours worth of straight listening on edge at the gym today, just to see the amount of data pulled, and how the battery held up. I also tested the player while driving to/from the gym. An hours worth of continuous listening at my gym (via edge) consumed 50% battery life, and about 50mb down data, and 1.5mb up data. FWIW. A few times I had to restart the uSirius player when it quit streaming. While driving, it seems that the player doesn't work as well, I guess it doesn't like switching towers. But still, not bad at all for BETA software!
If someone knows more about the feed quality, please chime in. I did a bunch of this 'stream quality' research when signing up for the standard radio account and the premium internet account in early 2007, and just regurgitating it from memory.
HTH.
