It let’s you pick from a whole bunch of local models to download, some trained by Microsoft and the like. In my experience it’s pretty responsive on a 2070s ive had for years now, but the responses aren’t as good as something like gpt4. Probably about on par with gpt3 in most cases if you choose a larger model.
IF you can find the song you want on Tidal, they have some actually very high quality tracks as FLACs
There’s also some services out there that let you rip from Tidal as well as other platforms ;)
