P.S. congratulations on the game relase! Spotify was asking me to login, so i think I found you on youtube, giving a listen. Perhaps consider updating your post by adding a non-spotify link?
CDBaby and Distrokid have a different model. Distrokid is effectively subscription based, with unlimited uploads of singles and albums as long as you keep up with your payments. CDBaby, by contrast, is more transactional. This works better for me, at least, because I do music as a hobby on the side, and so tend to release individual tracks sporadically, rather than entire albums. (Although having said that, I'm working on an ambient album right now!)
I'm certainly not raking in money through music streams, but I'm also not doing much marketing -- this post on HN is the most marketing I've done in the past month. ;) Unfortunately that means I can't really comment on how Distrokid compares in terms of managing payments etc.
