I know this is probably a sin for a bass players, but I don't honestly know if I have ever listened to a Jamerson bassline, as in I might have heard a song with him playing bass but I never really "listened" to the bass. Since I have heard almost all of the big names in bass, and idolize most of them

I figured I would've listened to him by now... but I digress... So what are some Jamerson "Essentials"?
P.S. - Sorry if similiar threads like this have been posted a thousand times. I searched a couple of times but didn't really find anything to answer my question.
