Here it is, I wanted to provide it yesterday but didn't have time:
1) (I have Music, is it even possible to still have iTunes? But that is a secondary question)
For advanced, with Music, I see no mention of media path, However, under Preferences> Files, I see:
/Macintosh HD/Users/MatthewStickler/Music/Music/Media
2) file:///Volumes/BUFFALO/612264/Music and Back-up/Music/iTunes/iTunes Music/Baden Powell/Os Afro Sambas/Aerosmith/Get Your Wings/01 Same Old Song And Dance.mp3
But, it's odd, I think I accidentally changed 1, yesterday to:
/BUFFALO/612264/Music and Back-up/Music/iTunes/iTunes Music/Baden Powell/Os Afro Sambas
Buffalo is the name/brand of the external hard drive.
3) /BUFFALO/612264/Music and Back-up/Music/iTunes/iTunes Music/Aerosmith/Get Your Wings/01 Same Old Song And Dance.mp3
So, this might be a bit confusing, in that when trying to "fix" it yesterday, I think I set the "Files" media path under Preferences, from
/Macintosh HD/Users/MatthewStickler/Music/Music/Media
to
/BUFFALO/612264/Music and Back-up/Music/iTunes/iTunes Music/Baden Powell/Os Afro Sambas
