When browsing folders, MP3 meta data (ID3 tags specifically) are not showing up. It seems only to be showing either the file name (minus extension) or the Title ID3 field. This screenshot shows AirPlayer in browse by folder view, along with another application which correctly shows the ID3 information:
AirPlayer should show metadata in Browse by Folder mode.
I have over one terabyte of songs, so viewing by "All Music" or even "All Artists" is not an option for me.
