I've been a lurker here, and I thought an app I created would be useful to some people on here.
My app is called Equator Music Player. It's is completely free and aims to use YouTube's large library and wrap it all into a music experience, not a video experience. It's super easy to find that one song with the card design, and the app just looks good. It's a premium experience at no cost. I personally made it after getting annoyed at Spotify ads and after realizing how inconvenient and disjointed YouTube's music experience was.
Here's the website: greatarcstudios.github.io/Equator-site/
Go ahead and check it out. I'd love some feed back. It's Windows only as of right now. Porting to Mac is a bit hard because it's tied into a lot of Windows binaries, which would require a large rewrite. I'm looking into making a Wine port though.
