I have an iTunes music library that I like to play on my new AppleTV (V4). Since this is the season, I have reviewed my iTunes library and made sure that all the Christmas music albums have a "Holiday" genre assigned (that's 21 albums). However, when I view the music on my AppleTV, and select the Holiday genre, I only see four albums - with most of the holiday music missing (though I can find the albums by browsing through the complete set of albums, though that is awkward given that I have 11,580 items in the library). One symptom is that when I check "My Music" in iTunes and select the Holiday Genre, I see all the music, but the songs for most (not all) of the albums are not consolidated into albums - songs in the same album are split into different sections - so that the same album shows up in multiple places. For example, the album "Winter Wonderland" shows up once for song 9, again for song 1, once for song 8, and so forth. My guess is the the fact that the songs are separated in this way is preventing the AppleTV from seeing all the albums. Any idea of how to deal with this?
