Favorite MJ song:

Off The Wall: "Don't Stop 'Til You Get Enough"
Thriller: "Wanna Be Startin' Somethin'"
Bad: "The Way You Make Me Feel"
Dangerous: "In The Closet"
HIStory: "Scream"
Blood On The Dance Floor: "Morphine"
Invincible: "Butterflies" (used to be "You Rock My World")

Favorite MJ video:

Off The Wall era: "DSTYGE"
Thriller era: "Thriller"
Bad era: Excluding the ones for "Man In The Mirror", "Another Part Of Me", and "Liberian Girl", I can't decide. They're all masterpieces, including the "Bad" video/short film if you ignore his laughable, bondage-esque outfit.
Dangerous era: "In The Closet", with "Who Is It" close behind. Every other video is either irrelevant or entertaining but overproduced.
HIStory era: Tie between "Scream" and "Earth Song"-- both overblown but awesome.
BOTDF era: "Ghosts", the full half-hour version moreso. I think it was trying to be another "Thriller" but it still rocks.
Invincible era: Only two vids from this era, "YRMW" and "Cry". Don't really care for either but "YRMW", I guess.

Favorite MJ moment:

Full-length Motown 25th special.

1995 MTV VMAs.
Well, I don't know if it's my favorite, but i became a fan around the first allegations and everybody declared him dead and burried and he came back kicking and very focused on his art imo. HIStory was, whatever it's flaws, big, with the promo and the scream song/video, and then YANA hit #1 and than MJ gave his first live performance since the scandal broke and he brought the house down. It's not his greatest momement, but it sure remains one of my favorites.

Fave momment, gotta be that Moonwalk at Motown 25 and also his MTV VMA 1995 performance. Music... his catalogue starting with Diana Ross presents the Jackson 5 all the way up to Invincible is phenominal, i love Dangerous and History and ovcourse the Q produced albums were fantastic. Video... gotta be Thriller overall but Smooth Criminal was pristine brilliance.
