I trusted Google Music Manager to download my music collection onto a new computer, importing the lot into iTunes. Only after I wiped my old computer did I realize that my music was now screwed up: Most any album featuring multiple artists was now split up into many albums. So Mr. Robot OST is about twenty different "albums", and it's become a pain to try to play a whole album in iTunes. How can I fix my songs?
I read some blurbs online about manually fixing an album, by checking the compilation box for each individual song. But I have a fair amount of songs to fix, so that would take a long time to do by hand! Can someone recommend an iTunes plugin or AppleScript or bash file to fix my music?
Assuming it's safe to enable the part-of-a-compilation bit on every song, even those that aren't actually part of a compilation, then I wonder if I could just loop over each .mp3 file and run some CLI app to fix the bits?
