In my collection I have several albums for which I don't have all the mp3s but I create the record for all the songs anyway. And when I go to the tab for songs on the artists page I see them all there. This is nice, but since we are gonna play them, how can we just show (on the songs tab), only those that actually have mp3's. The reason I ask this is because when you start playing the songs from the songs tab the music stops after it finds a song that doesn't have a file. This is not critical, does it make sense?
