[LongMan]

Thanks for the tremendous work that has gone into the database and smart playlists over the last few versions of Kodi/xbmc. I have noticed some unexpected behaviour in the smart palylists for music videos.
If I try to separate my music videos from those of the children, the result is not as I would expect. In each category only the actual videos from that category shows. However, all artists and their corresponding albums show under both categories.

For example
Kids Music Videos
Katy Perry (Katy Perry - Roar, Katy Perry - Dark Horse, Katy Perry - Last Friday Night, Katy Perry - Unconditionally)
Gwen Stefani (Gwen Stefani - Spark The Fire, Gwen Stefani - Hollaback Girl)
Pharrell (Pharrell - Happy, Pharrell - Hunter)

Main Music Videos
Bob Marley (Bob Marley - Buffalo Soldiers)
Maroon 5 (Maroon 5 - Animals)
Adele (Adele – Rolling in the Deep, Adele - Set Fire to the Rain, Adele – Skyfall, Adele – Someone Like You)
