Ok I'll play, I also have a HUGE collection of music, I have OVER 3,000 cd's not including what's on my computer, congrats to OP for having over 100gbs of music, that is awesome.
Some of my favorites in no particular order:
1. Orange Goblin - Coup De Grace (find this album!)
2. Beastie Boys - Check Your Head (this was the ablum that put them way ahead of the hiphop/rap genre)
3. Guns N Roses - Appetite For Destruction (not a bad song on this album from front to back)
4. Foo Fighters - s/t (again not a bad song on here)
5. Kyuss - Welcome To Sky Valley (massive album)
6. Fu Manchu - Go For It Live! (2 cd of live badassedness!!)
*edit* forgot a big one
7. AC/DC - Back In Black (a lot of people would say a Bon album, but this one is the 1st one after Bion died and once again not a bad song.....I love Bon too, so don't get me wrong, but this album can never go wrong no matter the setting)
Enjoy
