Here's some oldies but a goodies(80's, 90's and present). not all are bass lines, some have great beats (ya gotta remember, in the 80's and early 90's, base lines were hardly used to the degree they are today):
Gangstarr- Check the Technique, from Step in the Arena album
Folk Implosion/ KIDS soundtrack- Simean Groove
LL Cool J- Tha Boomin' System, from Mama Said Knock You Out
Any album by ICP (my personal favorite)
Bjork- Army of Me- Tank Girl Soundtrack/Telegram
Pop Will Eat Itself- Dance of the Mad Bastards, from Cure For Sanity
Kid Frost- Smoke, from Hispanic Causing Panic
M.A.R.S- Pump Up the Volume, no idea where you can get this...
The Police- Demolition Man, Ghost in the Machine
Anything by 3rd Bass
Q Tip- the entire Amplified album
Laibach- selected tracks from Das Kapital (really long, difficult names, since most of them are in a variety of languages such as German, Russian and French)
Sinead O'Connor- I Am Stretched on Your Grave, from I don't Want What I Haven't Got
Black Sheep- The Choice Is Yours, from Wolf In Sheep's Clothing
Gravediggaz- Bang Your Head, from their first album title (name???)
Limp Bizkit and DMX- Rollin' (Urban Assault Vehicle Mix), from Chocolate Starfish and Hot Dog Flavored Water

Korn and the Dust Brothers- Kick the PA, from the Spawn soundtrack
I'll think of some more...
