Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
