Not sure if many people have heard of or used this service, I signed up recently and it seems like a good new way to enjoy music and find new bands. The concept is pretty simple, if you've ever made a compilation tape or CD for anybody you'll be right at home here, users of 8tracks are able to put together compilations from their own collections based around any sort of theme they can think of, then share their selections online with other users, and obviously you can listen to compilations made by other people and search for specific tags, genres, artists or themes. I kinda like the way it works, I enjoyed Last FM recommending me music but this seems a bit more human as the compilations are put together by other music fans rather than a computer algorithm.
If anybody uses this site, or likes the sound of it and ends up signing up feel free to add and follow me, I'm still Demoniac on there and if anybody wants to post their own usernames for other people to add again feel free :)
