I just realised that at the moment I don't hear any background music. I do get sounds as in when I use my pickaxe or when I get a kiss, but nothing when wandering through a world. Also when Stoot suggested everyone play their music blocks at the appocalypse party on april 1st I didn't hear anything. So before filling a bug report I thought I'd ask, Should there be background music? (I do have both sound and music levels up to max)
