Try taking the basses out of an orchestra, take the bass tracks off all popular music, then see how important the bass part is. As far as playing the part goes, put any other musician on the bass and tell them to articulate the notes properly for each tune and genre and watch how they fail. Also tell them to properly do inversions at the right time, or play in the pocket and portray the groove. Then if that isn't enough, tell them to play a traditional country tune using the "less is more" style AND articulate properly. Fail, fail, fail. Bass ain't so easy after all.
