Its not really about the price (or lack thereof) that would be charged for a game, it is about the rights of the user who receives a copy of the software. Whatever the earnings model of a game may be, the point is that a free software license does not restrict the user's 4 software freedoms. Here is a link that explains it better than I ever could:
https://www.gnu.org/philosophy/free-sw.en.htmlIf you prevent the commercial redistribution of your game, whether by yourself, some member of the dev team, or by the end users who get copies of your game, you make the game non-free (as in freedom) by design. I believe when you say "we can discuss things" you are not talking about the music you have already made available, but about music you might make in the future as part of a game jam, etc. correct? Since this forum focuses on free-as-in-freedom games, you're probably not going to find anyone here who e.g. would want to collaborate on a game that wasn't going to be released as free software.
Importantly, free software doesn't *have* to be given away for no money, it just has to not restrict the freedoms of the user. For instance, the music that you released on OGA appears to be dual-licensed between CC-BY-SA and CC-BY (if I am not mistaken). Someone could sell those music files, alone or as part of a bundle, and as long as they followed the attribution and/or share-alike clauses of the license(s), they would be well within their rights. They would almost certainly make little or no money, since the files are available for free from your OGA account, but free software isn't about economics
I think this all must be a miscommunication. I like your music, and encourage you to make more
