I understand your problem, I am currently a massive fan of extreme metal but not a big fan of the bass lines, as you say a wee funky jam or what ever is more appealing.
Dont suppose it really matters though as long as you enjoy listening to and playing music in some form or other. You can always adapt playing as well, or use practicing one style to make you better over all, I know Alex Webster from Cannibal Corpse like to play through Victor Wooten stuff as well as supper fast metal lines.
