Is this an AI generated response? Spending 60 seconds on Google reveals every argument to be nonsense. A simple Google search for "OpenScore" reveals a MuseScore page with only 14 scores (all of which already exist in IMLSP). So what kind of "work" you think is happening there...I haven't a clue. Searching IMLSP for popular songs reveals mostly recordings and badly photo-copied PDF scores - nothing usable in the MIDI, XML, or ABC formats.
