Ok, this is a bit esoteric, but three CLASSIC tracks I am grooving on right now each have something in common.
Basically - a fat, deep baseline juxtaposed with a high pitched sound, like a vibraphone or a bell... the three tracks featuring this juxtaposition to great effect are
Hugh Mundell - Oh how I love H.I.M.
Delroy Wilson - Think Twice (discomix)
Lion Youth - Rat a Cut Bottle
Can you think of any more like these?
