This is an excellent site full of unusual (at least to my outdated ears) cutting-edge music. They make it very easy to either download or stream music, save your favourite playlists etc.
The amount of information about the music is unbelievable; there's even a guide to the history of each genre to ease you into it. An avalanche of "similar artist" links ensures that once you've found a sound you like, Epitonic will guide you to other artists and give you loads of new sounds to broaden your mind.
