How long is this likely to stay online? It sounds like it’s circumventing paid services (YouTube Music, specifically) - I can’t see Google being too happy about people skipping out on paying for their service.
(I’m not saying this is a bad idea, I’m openly wondering about the longevity of the app and slightly nervous about the dev’s wallet when it might come to a lawsuit. I don’t know if that’s a thing that would happen.)
“share” is obvious in what it does, and efficient in terms of using space on the website. I like it.
