Notice: If you've ever uploaded a YouTube video containing UNDERTALE/DELTARUNE music (especially gameplay videos) and receive a copyright notice, ALWAYS dispute it and it should be resolved in your favor. We apologize for the inconvenience.
I can only imagine that anyone managing youtube content for game music is as much a copyright nazi as the rest. You, sir, are almost unique in your stance. The only other studio I've seen that encourages reuse is Team Salvato
About 9 months ago I uploaded a arrangement of Megalovania but with every instrument replaced with samples of san's voice. It got claimed which I thought was fine since it's literally the full song but sans. Should I dispute it still or nah?
