Web version's broken. The menu's completely invisible, and the radio itself times out whenever it tries to load a song. (Apparently there's a solution for this issue since it's existed quite a while, but it requires changing Flash security settings, and Flash is no longer supported in most browsers). The "Go to Track" function is completely broken and spits out a 404 error. The other functions (minus the "Artist's Profile" and the one I'm about to touch on) don't work because Newgrounds has changed the formatting of it's URLs since this game was released. The only function that still works is "Add to Favs", and what good is adding a song you can't play nor even load up on here to your "favorites"?
While I'm sure there's a way to get it working again (probably just install Flash Player and the Newgrounds browser), there's not really a need to do so anymore since Newgrounds has an OFFICIAL radio now, which doesn't need Flash. I can't blame you for any of these issues though, so I'll still give you 5 stars since this was good while it lasted.
