Help with album art for playlist listening.

I have imported some playlists into Subsonic. They are simple .m3u files that list the directory and filename of a bunch of songs/albums in a particular order. Importing worked fine, and I can listen to the entire playlists in the web player.
However, for some reason Subsonic won't display the album art of the individual albums / songs within the playlist. It's grabbing the album art from the first song in the playlist, and displaying that for every other song in the playlist. Is this a problem on my end, or an intentional feature of Subsonic? Please help!!
Thanks in advance
