[ubuntu] Rhythmbox without GNOME -- library doesn't refresh?

view story

http://ubuntuforums.org – Is Rhythmbox supposed to automatically refresh the music library? I don't see any sort of manual "refresh" option, but files that I've added since originally importing the directory never appear. I run OpenBox instead of GNOME, so maybe there's a GNOME service used by RhythmBox that I don't have running? --Colin (Hardware)
