I put in "milonga" and it didn't know what to do with it. I put in "tango" and it gave me a bandoneon solo that meandered jazz-like -- it wasn't bad, but it wasn't tango either. For "vals" it gave me more of what it gave me for "tango". For "candombé" it gave me nonsense. But all the pre-canned stuff sounded pretty good to me. I guess if I was familiar with "Russian techno" I might find what Suno generates for that to be garbage.
