Is AUTHOR wrong in the post ? POST : There’s a particular piano piece I love so very, very much that has one particularly good transcription, but the author isn’t offering the sheet music for sale or otherwise. They did, however, post a synthesia (scrolling piano notes) video on YouTube for the entire piece, without including a MIDI, even though the title of the video said it included a MIDI file. I’ve been watching the video and tediously copying it into sheets for my own personal use and was thinking of posting the finished product for others to learn from. Many people would want access to it, and I’d be sure to give credit where it’s due if do post it (and wouldn’t dream of selling it) but still feel apprehensive as it’s not my creation. Still, the piece isn’t /by/ this person, it’s just their transcription of a completely separate composer’s piece. So. I’m a bit torn. I could make a few changes and call it my own cover, but that feels a bit cheap as there’s not much I could really tweak. What do you guys think?

TLDR;
A guy isn’t sharing sheet music he made and I’ve been making my own copy, WIBTA if I shared it?
