I'll note my own experience, that Spotify and Apple Music both struggle to find me latin reggaeton outside a small subset of popular artists, and my first couple searches with this tool have found me so much music I've never heard before that matches exactly the 'vibe' I want to hear, and is introducing me to different-but-related sounds and artists I couldn't have found on my own.

I agree with the other commenter - this is huge for me. Please, do whatever you need to do to monetize this so it never goes away. I would love to pay you for this.
