iTunes for iOS and it's ridiculous iNdexing...
As of iOS 8.4.1, the way the iTunes interface lists music is a bit silly. If you view your Library by Artist, you see the artist names listed alphabetically and the number of albums you have by them:
If you view your Library by Album, you get the albums non-alphabetically, organized by artist in alphabetical order:
So if I'm searching my Library under Albums, looking for "Aliens" (the movie soundtrack), I should find it not at the top of the current list, but under "J" for James Horner & The London Symphony Orchestra? That just seems a bit wonky to me...
