Suno (AI generated music service) – my experience so far (long)
0: A foreword - I'm not touching the whole copyright thing at all as I have zero interest in making famous artist X sing one of my songs, clone their music, or sending any musicians to flip hamburgers because I can't pay them to play for me; I write my own lyrics and, after having played for years in a rock band, just want to test the technology with an open mind. And.. yes, nothing beats the live/rehearsal room experience with real friends, instruments, sweat and lots of beer; no need to remind this old rocker about that:^)
1: Music genres available - There's lots of them, more than one can dream of, and they're so interesting to explore and combine; this aspect alone can have a huge potential in teaching music, if and when they'll implement a way to give the user more control over the AI. Unfortunately as it learns from the music available, it suffers from the "4 chords syndrome" plus if you're say a prog rock lover you'll have a hard time producing anything that is not some sort of metal in 4/4. I couldn't make it produce a 7/8 or 5/4, not even placing it along with "odd time signatures" in the prompt.
And consequently, prompting for metal and hard rock very often returns speed metal with annoying double speed drums. (to any suno engineers hopefully reading this: they're a rare exception, not the rule).
Apart from this and other possible quirks about other genres I'm not used to and can't comment, it's extremly rich and fun to explore. Also, it follows the indication if you write the era inside the prompt, that is, writing "rock, 70s, hammond pad, ..." will likely produce something that sounds like made classic rock of that era, and conversely makes possible things like "grunge, 70s, bagpipes" which of course will return something never heard before. That is what makes it interesting the most: sailing new seas!
Another problem: it's somehow obsessed with putting stupid synth solos in rock songs, and I don't mean a '70s type mono synth played Keith Emerson style which I would welcome in some tracks, but some obsessive repetitive loud patterns using multiple layered sawtooths like in many dance songs of a decade ago, that if you ask me, have no place even in dance music or techno (which I like). However I get them less and less with time, probably as a result of downvoting my own tracks that exhibit that problem; but that meant I smoked lots of precious credits for something that could be solved by having more control within the prompt or within lyrics. Trying [no synths] and the like of course didn't work. That brings us to the next point.
