The counter is great, thanks :)
I wouldn't overestimate the database because it's not really a db of music. It's more of a directory of links. And they lead to one of the finest examples of web2 Big Tech. Within 5 years, it can turn into a directory of links leading nowhere, and there's nothing we can do about that.
Besides, other restrictions apply. I live in the Czech Republic in the EU. When I browse YT, it only shows me content I can actually play here. Leo suggests songs I can't listen to. That is, from my point of view, a huge disadvantage compared to any similar tool which prevents me from actually using Leo Music. I guess many users will face similar issues.
