Please Add EXTINF to exported playlists

My car will use EXTINF data to display songs if it is in the m3u file, but playlists exported from subsonic don't contain any. Otherwise the car displays the filename. Here's a sample format:
Extended M3U playlist:
#EXTM3U
#EXTINF:199,In The Flesh
R:\Music\Pink Floyd\1979---The_Wall_CD1\1.In_The_Flesh.mp3
#EXTINF:217,One Of My Turns
R:\Music\Pink Floyd\1979---The_Wall_CD1\10.One_Of_My_Turns.mp3
The number after EXTINF: is the duration of the song in seconds. After the comma is the display name of the track.
More info here: http://en.wikipedia.org/wiki/M3U.
I also have to edit out the R:\Music when I copy stuff to a sd card but it's not a big deal to search and replace that in one command.
thanks
