Hi, I'd like to push for music support in the next Lix releases, and include these 5 tracks as oggs.
Minim, mobius: Are you okay with it? What license would you like?
Lix's code, tilesets, and sprites are all
CC0, basically public domain: The author waives all copyright, everybody can do everything they like with the assets. Random people from the internet may distribute, modify, or sell the assets without even crediting or mentioning us. I'm perfectly happy with that, but it would be egregious to entice you into releasing the music under CC0 without a clear warning what CC0 implies.
In case you don't like CC0,
CC-BY 4.0 is an alternative, or you can search the web for more options.
