"GMA SheetMusic" stands for: Games, Movie and Anime sheet music.
I make piano score that I sent to Youtube with Musescore and share the Pdf and Midi fileon this channel.
I do this because there are some scores that nobody has done or published on the internet (or I just didn't find it), or I didn't like someone else's version I found so I've edited it.
I also accept requests for scores you didn't find or found too hard to play.
