If you make music probably on here, SoundCloud or Bandcamp. I normally make a set of tracks and put them out there and use them in my own games as I see fit. I've only ever created 1 album from start to finish for the sole purpose of every single track is for a game

I've made heaps mate. No more for now. I used old Macintosh software to make them and I reached the limit of what I could make with it
