You should be allowed to cover Classical songs
Like Beethoven's, Bach's, Mozart's, Chopin, etc. This is ridiculous. Those are a century or more old songs. Everyone remixes those songs. Familiar melodies, but with the creator's flair. And, I thought the really cool thing with Suno also was, you could put LYRICS and SINGING for the songs you know and love the melody for. Want a pop version of In the Hall of the Mountain King with lyrics about darkness vs light? You could make that. Want a chiptune version of La Campanella with lyrics about the coming of age? You could even make that. And what about for songs that don't have very many remixes, or maybe they don't have a remix you want to hear, like Little Fugue in G Minor? Or Swan Lake? And I'm not saying you can't go into FL and go make the remix too. I feel that should be your decision. Don't know music stuff that well but want a remix you've been itching to hear? Suno. Have musical talent or you find it fun? FL. And, contrary to what a some people think, I do not think people who use Suno are 'lazy' or 'uncreative'. They still have put in a lot of work, even if it is a cover of a well-known song. Coming up with styles, making it sound good, titling, using Suno studio is NOT lazy.
And I know some people will agree and disagree on this. But I do want to defend the people who like to remix classical songs. I do not think it is right for them to be restricted because of 'copyright' for hundred year old songs.
