Average playing time of an LP = 20 minutes

Rotational speed of an LP = 33.3 rpm

Hence, number of rotations = 666

Coincidence? :-)

Nice number crunching Stewart:-))
Few vinyl sides are 20mins, much closer to
25mins.

I just hastily added up the running time of my 1500 vinyl albums and the
average was 19.5 minutes

You did WHAT?!!!
