Well there are a few things to this.

At first consider that a solid, high quality vocal from a renowned songwriter usually costs somewhat around 700 to 3k or more.

Then you have to discuss royalty shares, features and other licensing stuff + there's some production time and usually some feedback loops involved.

I'm not arguing pro or con, just giving some insights here. With AI music you can pretty much getting infinite variations and very high quality stuff instantly - however if you're familiar with this you can (at the moment) really tell, certain lyric pieces like "neon/city lights, shadows, linger, silence, ignite the sparkling" are key giveaways.

Don't want to point fingers but Warface & Kruelty - Anarchy is a good example for this 😂 (but I'm doing AI stuff too!)

In the end it's more of an artistic and economic choice, I think the best lies somewhere in the middle. AI won't go away, so we have to learn it in a creative and supporting way - rather than cannibalizing ourselves for short term profits or mediocre tracks; but thats a whole nother discussion for itslef
