There "might" be. But people aren't using things responsibly. It just doesn't happen. And the downsides of AI, especially in anything related to arts, by *far* outweigh the possible benfits.
IOW, while I perfectly understand how you could use Suno (or your hypothetical AI-jam-band) in a productive fashion, this isn't happening.
What's happening is that we're giving away centuries of cultural heritage to an uncontrollable monster (and yes, that's in fact an appropriate word). We can already see the outcome of this. And it's not going to get any better, more to the opposite.
The entire professional music production scene will be completely destroyed in not even a handful of years to come (sure, live playing will survive for quite a while to come, but younger folks - at least over here - aren't that much interested in it already anymore).
And it doesn't stop there but will as well have an impact on our mere amateur-ish circles.
I'm kinda active in a german forum dedicated to (mainly hobbyist) recording and related things. You won't believe how many people have already been "busted", using Suno tracks while pretending they were their own. Or rather: Most often these folks just don't even say anything about how things were created (which is what that forum is a lot about) and go completely silent when you ask them.
For a whole number of years, you could do your thing in your home studio, then post it for some 50-ish listeners and at least get some criticism or some positive feedback. Which is just terrific to keep you going. These days, it's all completely obsolete because you're just buried in the massive output of at least partially (often fully) AI-created "productions", which by now are even coming along in incredible quality (both musically and sonically).
So, why exactly would you keep going with your home productions when a few clicks could generate dozens of better sounding things in seconds and when your small potential audience is by now reduced to zero because of the inflationary amount of AI music?
Sure, there's the value of the creative process, but it's still getting increasingly frustrating.

Then, as it has been brought up: "Technology has always destroyed jobs!"
Very true. But what's happening right now is new for a number of reasons.
When blacksmiths were about to become obsolete because cars were the new hot thing, it didn't happen overnight. It took about a generation, so if you were a blacksmith you were able to prepare your son to not become a blacksmith as well.
But when you were an aspiring, say, graphic designer just 5 years ago, chances are that you're out of jobs today already.
Things right now are happening at a pace that us mere humans aren't able to follow or adjust to anymore.
And as said above: We're just giving away our cultural heritage for nothing (but a little bit of quick success for a handful of folks).
In a very small amount of years, we'll be flooded with movies starring Charlie Chaplin as the new 007 and Marilyn Monroe as the new Bond girl, with Fritz Lang being the director and the score being created by a mixture of Hans Zimmer and the Sex Pistols. And it will all look and sound absolutely real.
Writing will be affected just as much. If you are into, say, realistic historic novels, who do you think would be the best to do the required research? Certainly not a human being. And you could have it written in any style between John Grisham and Douglas Adams.
And none of that is in the far future, because all of these things are happening right now. You may still be able to distinguish between real human and AI works, but it's a matter of a handful of years (at best) for that to become completely impossible.

So, in a nutshell: When it comes to AI (at least in all areas somewhat related to creativity), no, I'm not black and white. It's full stop black.
Sorry for such a long OT post, we should possibly have a dedicated AI thread indeed. But to get more on topic, how about requesting Line 6 to come up with a direct link between Showcase and Suno? You might not even need to play through your AI created presets yourself anymore. Heck, you could just have someone setting up a Stadium and a holographic avatar of yourself for your next gigs. The advance being that you could even play multiple gigs parallely. Come to think of it: The Stadium could as well just be a holographic avatar.
