A mathematical law, regarding dance records.
"The product of R and C is inversed proportionally to A."
where
R is the
rarability of the record,
C is the
credibility in playing the record,
and A is the availability of the record.
This means that finding a
cool record to play that your
cool DJ pals will respect you for playing, is utterly
impossible.
