This is the part where I don't really understand the purpose of this. You create something, and then upload it to the AI to lose copyright protection on it; meanwhile feeding the AI your original material. What is there to even gain by doing this? We have plugins which will generate notes and chords, harmonies, melodies, or anything else you might want to use instead. They will get you past some kind of writers block situation too; just with some more work. Even if you do get some musical parts from AI, why wouldn't you just deconstruct them to make them into original material again, like you would with Midi files or Samples?

 

If you have a premium subscription, yes, you still hold the rights. However, suno holds the right to train on your music the second you upload, as well as whatever is generated.
