I found topic about PANDORA (internet radio) on this forum but...
any of You have ever tryed last.fm
As far as i know to listen PANDORA u have to use their web page...
but to listen last.fm u can easily download their small program and enjoy very new music...
More to that last.fm give some info about bands/musicians u listen to.
U can type artist name or just a tag of music u like.
I hope some of You will try it
(its basically same thing like pandora +a bit something more)
U can make something like personal "what i've been listening" or "recently played" list and put it on website or forum.
example of list on my website
If You need some more info feel free to put question in this topic.
