It's good, I have this song I generated last year with Suno which stuck with me and I just tried having Flow generate a variant and it was acceptable. Sometimes the lyrics get modified for no reason. It would be better if you could control emphasis by specifying tags or something along those lines, but it seems fun to play around. If there was an intermediate step where a symbolic or partial processing of your input was shown for tweaking, it would be immensely powerful.

One of the key issues that I encountered after a few song generations is that it feels very rushed, like it's constrained to this 3 minute limit per song so it forces every section of the song to conform to a very specific structure. I tried increasing the limit to 4 minutes but it still gave me 3 minute songs.

Honestly, I feel like this product is showing up a bit late to the party and it's not really feeling particularly innovative. There's nothing egregiously bad about it, but it doesn't seem to add anything new or special that I could notice.

I don't have a microphone hooked up so I can't try the voice interface, but it would be really fun if you could sing to it in order to iteratively compose a song. It could clean up your voice a bit and add music. Or being able to hum out a beat which it converts into a track which you slowly build up. Is anyone able to try if those capabilities are possible with the existing product?

Overall, I'm not sure if a chat interface is the best way to produce a song. It feels very restrictive to have full songs as the primary iteration mechanism. In a text file and in code you can inspect or modify different sections or components very easily. I think a more human-focused tool would provide an on-ramp towards full music production, where you can focus on the parts that you care about and enjoy, while the AI tool fills the other parts with sausage. Right now you can chat with the tool but it appears to be quite limited in the kind of changes that it can make.
