This is my biggest playlist on spotify. It has LOTS of good IDM. And I should stress the "et cetera" since there is also reggae, hip hop, acoustic stuff, indie and other chill stuff that seems to share an atmosphere nonetheless. Besides all this expect to see trip hop, trance, industrial, drum and bass, dubstep.
In a way I feel it might be impossible for a lot of people to like every single genre contained. But it's probably good for getting into stuff similar to what you do know in the playlist?
