Comparison of audio streaming applications, radio or otherwise

[bastian74]

Please post the audio streaming applications you've used and the primary features they have. Something that can work with the touch pro 2 obviously.

I imagine 4 different categories:

Streams random songs in a category (pandora-like)
Streams radio stations (wunderradio-like)
Streams specific songs (grooveshark?) Grooveshark doesn't work for me so I'm not clear what it does.
Streams your own MP3s from your home computer (does this exist?)

Of course you can use skyfire to stream any web-based content, but I don't know of a way to boost skyfire's audio compression. Is there?

And uhh, music tv stations via a slingbox? Again, a waste of bandwidth / poor quality audio.
