Two years ago, AI music was a party trick: short clips that sounded like a robot humming through a fan. This week we added Suno to the MustUseAI directory because that era is over — its v6 models now produce full-length songs with real vocals, structure, and mix quality you can actually release.
What earned it a Must Use badge: a genuinely generous free tier (50 credits a day, about 10 songs), and paid plans that grant real commercial rights — Pro costs $10 a month and Suno takes no cut of your royalties. We verified pricing against Suno's official pricing page in October 2026, and as always we mark it approximate because AI pricing changes fast.
The honest caveats are in our full review: free-tier songs cannot be used commercially, paid plans have monthly download caps, and the music industry's lawsuits over training data are still playing out. None of that disqualifies it — but you should know before you publish.
AI music is becoming a real category, not a novelty. We will keep watching it — and if a rival beats Suno on value, we will say so and update the listing.
