Probably depends on my mood but I could listen to very different stuff across many genres, but it's cool to have something that's obviously not distracting. Lately I've been listening a lot to 65daysofstatic's No Man's Sky score, or It Follows by Disasterpeace, or Nisennenmondai, and Myrkur... Ok, that's actually a lot of dark stuff but I also like to listen to something more lively and fun like Oh Land or La Roux, lyrics don't really bother me. Also, friggin Iron Maiden anytime, go figure.
