is anyone familiar with ELLO music? theyre making claims on a lot of videos lately and using my undertale covers as a match. @MateriaColl any ideas?

Most likely it's YouTube's display bug: YouTube uses cover songs of game music to match melodies, since original game soundtracks are ineligible for royalty/compensation, hence covers are shown. If you send over more info to info@materiamusicpub.com our pub team can investigate
