Looking at the Wiki article for "1984 in Music", here's what I see as albums I enjoy from that year...
1984 - Van Halen
"Weird Al" Yankovic in 3-D - "Weird Al" Yankovic
Fugazi - Marillion
Three Of A Perfect Pair - King Crimson
Grace Under Pressure - Rush
The Best Of Kansas - Kansas
The Unforgettable Fire - U2
And even though I've only seen the movie and don't own the album, This Is Spinal Tap by Spinal Tap should soon be owned by me because I find the movie HILARIOUS...
