I am a great fan of foobar2000 and the mobile version (1.2.8).
With the latter I would like to have the information about title, album and artist taken from the tags of flac files, like mp3 files.
Currently only the filename is displayed.
Not sure what you are doing, but when you add a location or folder and rescan the collection is indexed and you can then browse by genre, artist, album etc. Perhaps you are browsing files by folder?
