Good start

User Interface: 5/5
Ease of use: 5/5
Does what its supposed to do: 3.5/5.... Sometimes you would have to log in and out otherwise you wont find your files or wont be able to open them.
Support for iTunes m4a format would be nice
Actual player for media would be great too (option to play all files in a folder, or at least to pause a song or scroll)
