The big secret right now is Suno will output good stuff but then it’s tortuous to get the lyrics to line up if you want to change anything, or add a word, it screws up the entire flow of the song all the way through. I spent 5 minutes making a 6 minute long power metal style song about a Druid fighting a dragon, then two hours unsuccessfully trying to get one with slightly more coherent lyrics and it output like 8 songs that sound terrible in a way I can’t quite put my finger on. The one song I tortured into existence took me 5 hours of work after getting a rough draft.
That said, being able to instantly make a song to tell my kids they need to clean the living room before we open presents and them singing the chorus happily for weeks after is just this great unique memory we have. Bespoke songs just for us is one of the coolest things ever and no amount of grumbling from anyone can dissuade me from it.
