I think I’ve been listening in the wrong order….

I haven't listened to any of the 80s albums, with the exception of Sign O the Times. I don't know really any of his songs from the 80s at all. I started at Diamonds and Pearls and have listened chronologically since then, working on Rave Un2 the Joy Fantastic. I listened to Sign O the Times after Emancipation, and it's honestly kinda hard to go back once you're used to his 90s stuff. Where should I start with the 80s albums?
