Bloop is a site to upload your MP3s and stuff. Good way of sussing this out is to click on a random bloop account.
Searched for "bass" and it come up with a load of techno and drum n bass.
Dred Bass - Technology.mp3
But!!! The blue button doesn't work for MP3s from Bloop. You have to click on the track title. It then loads in a new window and starts playing straight away. Pretty cool.
