It’s not an expression of yourself at all. It’s an expression of the AI that you rubber stamped as yours because it sounds cool and is close enough to what you’re looking for. As a lifelong musician, I enjoy playing with Suno, but please don’t convince yourself that you’re one of us because you typed a prompt into an AI.

That's the value of constraint.

People regularly compose symphonies that aren't playable by any orchestra.

If a human can't play it or it can't even be played in theory on the instrument, then is it really self expression? What is being expressed, exactly?

This is getting to the core of what music is, and isn't - and part of what music is is an expression of mastery of craft.

Can it really be called an expression of yourself when you don’t write the lyrics or have any musical input on the song? This sounds more like having an idea for a song rather than an actual expression of yourself.

Would you still call it an expression of yourself if you paid an artist to write a song for you around an idea you had? I don’t think most people would generally refer to it as “expressing themselves” when they commission another artist.

...you express yourself still. Art isn't about a mechanistic and functional product that needs to be "good", but what's on your mind, and often those imperfections add flair and a human story to the end result. There's tons of pop music created by people who don't even know music theory and are just messing about

Uh, too bad for them? What if I want a hot muscular body, but don’t want to spend the hundreds of hours running, lifting weights, planning and executing a healthy diet; and I certainly don’t want to use steroids?
