So the music you got a copyright claim for is a track I purchased the rights for from a site called https://www.themusicase.com/ The track is Spanish Matador Of 21 Century by Alex Khaskin, and the rights I bought allow me to use the song in any non commercial project. Seeing as how I'm not charging people for my game, nor am I accepting Paypal donations, I didn't foresee this being a problem. I was of course planning to hire a composer later on in the game's development when the game is closer to being commercially viable, and was planning on purchasing Royalty Free Music to use until a later date.
Thanks for letting me know though. There is of course an option in the game's menu under the Audio tab to mute all of the game's music, if needed. I'm very sorry to hear of the Copyright claim on one of your videos because of this. I know Youtube is kind of infamous for DMCA claims that have been a headache for content creators. Guess I'll have to consider perhaps removing the track if it's going to cause problems for streamers.
Much appreciated, and best wishes!
