Why the bass is so important to music in general, even though it doesn’t sound loud in most songs?

Question

I feel it “fills” the song but I dont know how to express this in better words

Answer 1

In club music you get 16 beats to a bar, for most of the track you get 12 beats of bass then the last four are a recognisable buildup then a bang as the first of the next 16 beats. This is a consistent pattern that is used to know when to cue up another to mix in or out to. You can use head phones listen to the alternate track whilst counting the beats of the track thats playing and as not all tracks are recorded at the same speed (or played at the same RPM) the bass then is a distinct marker that helps to know if one track is going faster or slower.
