Wow, 50 tracks is a lot! Have you considered embedding them on the Itch page using YouTube/SoundCloud to provide a sort of preview? I've seen other composers do this and it's handy for getting a sense of whether the music will be a good fit for any given game.
Viewing post in Just released my FIRST project!!!
once I upload them to those platforms then it’s free for everyone however I am allowing use for free if downloaded - once I make public in my SoundCloud some person who isn’t making a game could use it (not my goal).
just has happened to many times however if I was charging then I would do this 100% but that’s a BIG reason I am handing out free!
