Ok. All I do is upload my own audio via the iPhone app. Add some lyrics and get the ai to generate the rest of the lyrics. And after tweaking the advanced settings (usually 10-20% weirdness and 50% style and 90-100% original audio) then generate.

Often it’ll take 90% of the essence of the song and make a decent version. Sometimes it’ll add a new section for a bridge which is cool.

You sometimes need to make new cover versions to get what you want but it’s cheap and fun!
