One of the most important features of foobar2000 is the possibility(!) to browse the music library by your own file system folder structure (View > by folder structure).

I really don't like mp3 player software that prevents the user from structuring the library after his own fancy in the most classic, portable and platform independent structure there is: The file system structure, i.e. folders and file names.

I hope that this feature will be available in the Android app, too.
