Music on Apple TV 4th Gen not displaying genres correctly

Running OSX 10.11, Apple TV 4th Gen. I use iTunes and have a meticulously managed media library. All mp3's are sorted properly by artist, title, etc, and tagged correctly. I use genres in iTunes for music, and have validated they are correct in iTunes.

When I view music on my computer in Apple TV, under the Music section are any available playlists, genres, etc. If I navigate to the Soundtrack genre, in this case, it is littered with random songs, and even some albums that are in no way soundtracks, nor tagged as such. I haven't checked the other genres in Apple TV, but wanted to mention this issue before I forgot.

This is troubling, especially for large libraries that enthusiasts such as myself spend a lot of time managing. Anyone else see this?
