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. Many classical sides are 30mins,
and nicely accommodate the three movements
of a symphony.

Hence, number of rotations = 832 (or even 999)
Shall we change the name of the thread to "vinyl is magic":-)

Cordially,
