MiniTV!
where it just sits on your (Vista/Win7) desktop as a widget and buffers channels from random places. mine’s permanently at SonyMusic.~

yea, the screen’s a bit small, but at least i dont have to keep track of random URLs. also, it’s expandable.

(that singer reminds me of Kitade Nana, but with that ridiculously pale skin it could be Kosaka Riyu for all you know! doesnt sound like Riyu tho; her voice is kinda distinctive. kinda.)
