I'm more into the electronic side nowadays, moreso than the rock. I'm just going to make a huge list of artists for you here, maybe I'll get around to actually posting them on hubski sometime. Let me know if I'm missing anything obvious, haha
The electronic is pretty eclectic; not all of it is as chill as Tycho. I got most of it from reddit's /r/futurebeats.
