I consider SelectRadio to be the best streaming software as it already has all the last.fm, shoutcase, xm, sirius, and other streams loaded into it.

Unfortunately the most recent ROMS (more current base) seem to have broken it and it closes after 1 minute of use (others have confirmed this).

My second choice is Pocket Tunes which has all the shoutcast and last.fm stations already loaded but also functions as a regular media player as well.
