I'm looking for a music player/music library manager that allows me to see a list of artists sorted by the number of tracks I have for that artist. Winamp does this, but I haven't found any Ubuntu-compatible applications that will. GMusicBrowser comes the closest.
I've tried Banshee, Amarok, Guayadeque, Audacious, and looked at screenshots for a bunch more (Clementine, Exaile, Quodlibet, Jajuk, etc.).
Again, I'm looking for the ability to sort by how many songs I own per artist.
Alternately, the ability to show a filtered list of artists based on the number of tracks (e.g. show me only the artists with more than, say, 10 tracks) would work.
