Last month we had the chance to play around with LauncherPro developer Fredrico Carnales' latest app, UberMusic. I, personally, had a great amount of fun with it, as it evokes a certain "Zune" feel while remaining largely functional.
The app's left its open beta phase and is now available on the Android market for a price of $3.49; for a music player that pulls in album art and artist data, I'd say that isn't too bad of a price.
It also looks like there's been some UI changes to the Artist and Album sorting, as well. Albums show up with their art individually, and everything looks a whole lot cleaner. The screenshots on the marketplace actually show multiple configurations to the same screen, so there should be something here for everyone.
Numerous skins have already been made for the player, which are searchable using "Ubermusic skin" in the Android market.
