the hype machine. my friend ted told me about this awhile back, but i'm just getting around to checking it out. basically, it searches blogs and forms a list of what bands(mp3s) are being posted on the net. it's even set up so you can listen to the mp3s with various players as a sort of random playlist. i haven't tried out that function as i usually have too much to listen to anyway. there is also a search function so you can see who is posting about pizzicato five, madness, martin denny, etc.
