It would be nice to control which tags get added to the playlist tags that are generated for the "External Player with Playlist" option.
IE: Currently it displays the track time, the artist, and the track title. I'm assuming this is due to limitations in the m3u format based on this... http://en.wikipedia.org/wiki/M3U
I would like to see the album as well and possibly other data if supported by possibly adding support for XSPF to be the playlist generated. http://en.wikipedia.org/wiki/XSPF
