I have raged at Sibelius numerous times when I was told “It’s the best music notation software out there.” Finale, the other big corporate music notation software, touting itself as more user friendly, has a garbage UI. It’s because of this YouTuber that I found out about MuseScore (for which he’s worked on the UI), and I was psyched to see he’s part of Audacity as well. I’m fully switched over to MuseScore now, and I’m staying there. Plus it’s FOSS!
