Feature Request here: like, have it let you pick your own song via files (and add a "convert to .abc" button so it'll play. The UI style can be like Starcheat's or LuAnimator's, but you can choose that (open up a seperate window not ingame for these features)

You cannot access to files which aren't in starbound assets (mods included).
For .abc files; I need to check, but I don't think it's possible.

@moomal : By default, the music is infinitly playing. I'm working on playlists right now

What I wanted to do is making a quick tutorial about how to create a "fake" mod which would allow you to add your own musics (.ogg only) to JukeCrate playlist
