I've made a few tracks using Suno to scratch my own itch / desire for music that covers certain themes.
The best use of Suno for has been the ease with which you can generate diss tracks: I ask Gemini to make a diss track lyrics related to specific topics, and then I have Suno generate the actual track. It's very cathartic when you're sitting at home in the dark because the power company continues to fail.
Anyway, I hope I can get access, I think it would be fun to vibe some new music. Although this UI looks severely limited in what capabilities it provides. Why aren't the people who build these tools innovating more? It would be cool if you could generate a song and then have it split into multiple tracks that you can remix and tweak independently. Maybe a section of track is pretty good but you want to switch out a specific instrument. Maybe describe what kind of beats you want to the tool and have it generate multiple potential interpretations, which you can start to combine and build up into a proper track. I think ideally I'd be able to describe what kind of mood or vibe I'm going for, without having to worry about any of the musical theory behind it, and the tool should generate what I want.
