Some of these answers may change every time you ask, but here’s my answers as of right now:
Tool - Fear Inoculum
Radiohead - OK Computer
Deftones - Koi No Yokan / Ohms (I really can’t decide between the two)
Queens of the Stone Age - debut self titled album
The Strokes - Is This It
Guns N’ Roses - Appetite for Destruction
That’s five, right? I suck at math.

VERY honorable mentions:
Stone Temple Pilots - Purple
The Strokes - First Impressions of Earth
Tame Impala - Lonerism
And last but not least, and this is an album that basically no one has heard that definitely belongs in my top five-ish but I don’t know which album to pull off the list:
Tilts - self titled
I cannot say enough good things about this album. One of the very best rock albums to be released in the last 20 years. Criminally unheard. Starts strong and just keeps getting better with every song.
