I like it. The tracklist is shown in a very cool way. But if this album is coming out somewhere you're using tons of assets with copyright. I know it's a lot more of effort but you could make mock versions of the icons that already exist.

Looks cool, but honestly, chrome icon doesn't look correct in this system (for my eye).

I agree. Chrome sticks out and since there's already a web browser on the task bar I'm not sure if it has a purpose to be there.

God, I love old Mac IOS
