I use SUNO extensively. It is very good at creating arrangements far beyond what you can do in BIAB. The quality is not quite useable yet but it will be in a year or two.
But I use it differently than some. I create a track in BIAB. I bring it into Studio One (now Fender Studio Pro) and record a vocal track. Then I upload it into Suno I add lyrics (it doesn't always detect my sung lyrics. Then I run the appropriate prompts in the style section and the lyrics. I use a voice clone of my voice - a recent addition to Suno. It doesn't always sound like me. Curiously it sounds kinda like Dr. John. After I run a dozen or so iterations and change things along the way. Being able to hear your lyrics in a more polished arrangement is very useful. When I'm finally done, I have Suno split the stems. Their stem splitting is very good except they're splitting parts of the overall song because Suno doesn't create tracks, just a stereo song. There's usually a stem called FX or other and it sounds like noise but if you remove it you lose part of the instruments. I bring the stems back into Studio Pro. I can use their extract to notes (midi) on any tracks I can. Some work, some don't. I use a plugin called restem that splits the drum stem into separate stems. If I'm lucky ReStem will identify the ride cymbal and I can separate that an extract it to midi and put a decent ride cymbal on it. I replace as many tracks as I have the ability to do on guitar and keyboards. It's a lot of work. Far more than I would do using BIAB and Studio Pro, but the end result is really good. And the quality passes my car stereo test.The ultimate test. As I age I lose skills on real instrument. I also have parkinson's which robs me of my playing ability. So I think that my skills will decline in direct comparison to Suno's improving quality. I am sure I will at some point only use a BIAB backing track and Suno to create music. I think using Suno is a creative process. There's a lot of Suno slop out there. Its very evident to me when I hear it. There's also some really good stuff. Ai lowers the bar for music production. People have inherent musical talent but for whatever reason they can't play an instrument will be able create quality music. Maybe the next George Gershwin or Ray Charles is out there but can't play an instrument. Both Gershwin and Charles were fabulous musicians but what we remember is their songs, their genius. Thank you for reading.
