I've been listening to Mitch Murder's Selection 6 lately. Makes for great music to work or relax to.

I also like to shuffle Rocketchip's tracks. I think it's a very small group, maybe just one guy. Chip tune bands are a dime a dozen, but I feel like Rocketchip does a great job at taking you on a journey. It never feels repetitive, it's always varying the melody enough to stay interesting. Wish they would put out a full album.
