Unfortunately there isn't a demo for UberMusic, yet, but ever a person who is always willing to try out new a music player (I breath and live music), I decided to give it a shot on my Samsung Galaxy S II. Starting it up for the first time will bring you to the library menu where you can swipe sideways to choose between Artists, Albums, Songs, Genre, Playlists and Folders. This works similarly to how the Zune player works. Selecting an artist will bring up a sub-section which includes their albums and a biography. Further more, the app will download a picture of the artists to use as a background during playback. Music can be scrobbled through either the official Last.fm app or ScrobbleDroid/SLS.
UberMusic costs US$3.49, which is a lot of money to pay for a music player. Personally I think it is worth it because not only do you get a music player with a slick UX, but it also performs fantastic. Yes, it is a bare bones player features wise, and there are many more players on the market, both free and commercial, that are more powerful and decent alternative to the default Android music player. I do urge you to check them out. In the meantime I highly recommend UberMusic for people looking for a minimalistic and easy to use Android music player.
