Yes, I noticed that Claude Code silently refused to generate lyrics for some songs i requested. Benefit of this approach is that anybody can quickly generate a YAML file for a backing track, no need to share it anywhere.
I think the problem is that the artist doesn't get anything with this approach. If you really want to use someone else's music/artworks/lyrics, just buy it.
It's not like this is very unique, YouTube has tons of training and backing track videos, which is what i typically use. And artist don't sell it in a way that can be consumed for guitar practice easily.
