Under "Artists" the Compilation does not contain my "part of compilation" songs. It does however list every Artist even part of compilation under "Artists". Itunes 10 would not list my Artists that were part of compilations, and "Compilations" would contain all marked. Is this a bug in iTunes 11? Are there more than just me how has this? Kind of created a mess here. And not sure how to go about fixing it since the music is properly tagged.
