Maldi: I totally know what you're talking about!
I was listening to Canned Heat, closed my eyes... Felt like I was in the middle of a disco in the 70's... Although I didn't even exist back then :P
And Virtual insanity is one of my fav songs of all time

Loach, since I pretty much like all their stuff, I probably won't be much help lol.
And I can't help but to lean towards songs with cooler bass lines rather than a good overall song (I have bass ears ._.)
If you like Virtual Insanity, you'd probably like their newer stuff so try these songs:
-Travelling Without Moving
-Deeper Underground (the intro is a tad long but I <3 it)
-Canned Heat (If you've seen Napoleon Dynamite, you'll know this one )
-Runaway
-(Don't) Give Hate a Chance
