A second point about recognizing harmony:
The reason that you tube bit works musically is that for a given progression, you can produce a reasonable approximation with simplfied chords.
there is an approach to harmonic theory that seeks to treat every harmonic variation (within a single key) as either a I, IV or V.
A I - V - vi - IV would probably work almost as well (with the melody) as a I - V - I - IV
Because the I (
CEG for example) shares tones with the iv (A
CE)
There are many "easy piano" or "easy guitar" books that present "reduced" version of popularsongs, where the chords are reduced in a similar way.
So an active listening approach could include simply trying to hear if the chord change is going to a Dominant (I-V) feel or a Subdominant (I-IV) feel.
Which doesn't mean that as a bassist you can freely change any song you're playign to a simplified combo of I, IV and V.
In fact, youre role as a bassist, with control of the root, could be seen preventing that from happenig
