Midnight snacks is pretty much the best music podcast I have found. It's been going on for damn well three years, and all of it is solid gold.
It's tagged with things like "avant garde, breakcore, chiptune, doom metal, electro, hip-hop, idm, industrial, j-punk, j-rock, jazz"
But, like. It's all really fucking good. Some of the best music I have listened to has come from this podcast.
If you like that electronic music thing, Go check it out.
