I personally don't see a reason to torrent music when a simple download of a flac or something from yt if I can't find it anywhere else is usually fine. But I will say I'm more likely to pirate music from large artists/companies because I don't support large record companies and their shitty practices.
Similar thing goes for things like Vocaloid, UTAU/OPENUTAU, Synthesizer V, DeepVocal, etcetera, songs because the majority of the time the songs I'm listening to don't have an official download (or a link to a removed file) or way to get it through supporting the person who made them.
