AI Songwriting Assistant?

I'm trying to validate an idea. Obviously, there are tons of AI tools that will write lyrics or generate music for you. I'm looking to do something a little different.

Songwriters take pride in coming up with original melodic and rhythmic ideas, as well as writing authentic and human lyrics. No self-respecting songwriter wants to use AI to create music. But what if you could use AI as a tool to provide inspiration, or help you when you're stuck?

The idea is an AI-powered songwriting assistant. For example, play a melody or a few chords, and it could detect the key and suggest chord progressions or additional melodic ideas. It could even generate a backing track for you to jam to and further refine your ideas.

For lyrics, it could serve as a basic rhyming dictionary (give me words that rhyme with "beer" for my bro country song), or even suggest a verse when you're stuck. If you have a melody but no lyrics, perhaps it could even generate lyrics in a particular style so you can record your melodic idea.

The generated music or lyrics aren't meant to replace your own songwriting efforts (although there's nothing stopping you from using them), but to augment your own creativity. Any music or lyrics generated are meant to be disposable.

Obviously, musicians and songwriters are wary of AI, as much of the current AI tech seems intent on replacing human endeavor. (I'm a software developer, so I get it.) On the other hand, I've found that AI can reduce the cognitive load of doing repetitive systematic tasks, such as determining the key or chord progressions for a song, or producing backing tracks for rough demos.

There are lots of AI tools that can write music for you, but very few that actually help you write music. Is this something that songwriters would be interested in? The idea is a mobile-ready web app with a reasonable monthly fee.

I'll put on my flame-retardant suit and wait for the downvotes.
