Awesome, what's the licence ? :)
Well it's a soundtrack I made for a gamejam game as part of a team. License wise I'm not completely sure what I'd classify it as because I'm not 100% familiar with the different license types. It's free music to download but that's mostly for promotion of the game and my music, not so much for other people to put in their games. I'd have no problem with the music being used in a video on youtube or twitch etc. as long as it was credited/linked to. If you give me more details of what you'd like to do with it I'm sure I could help you out :)
Well personally, I would have no problem with you using some of the music in a free game. However when it comes down to the fact that I made this for another team it becomes a bit murkier if you get what I mean.
I personally don't know if they'd be happy with me licensing out music I made for them to somebody else.
If it was a free game on Itch.io I imagine I could work out a way that you could use some/all of it after chatting with the team members. With donations enabled would be fine unless you somehow ended up making a fortune out of the game.
Again I’m not 100% sure if I could negotiate this, but I would do my best to try.
I don't really know if it'd be possible to convince the team to let you use the music for a commercial game, and even if they were, I'd want some kind of financial deal/contract with you.
