The most common note is a quarter note, this is true, however half notes take 2 beats, whole notes 4 beats, dotted notes take 1.2 times whatever time period they would normally occupy (IIRC - its been a long time since I was a competent dot follower) etc.

So going to back to the riff for Satisfaction in tablature:

E-|-----------------------------------------------------------|
B-|-----------------------------------------------------------|
G-|-----------------------------------------------------------|
D-|-----------------------------------------------------------|
A-|-2--2----2--4--5----5--5--4--2--2--------------------------|
E-|-----------------------------------------------------------|

it is quarter half quarter quarter half quarter quarter quarter quarter quarter

Timing of notes is just as important as pitch in determining recognizability/melody.
