A mathematical law, regarding dance floor content:
"As P goes towards infinity, C goes towards zero."
where P is the playability of the record,
and C is the credibility
and respect that the DJ
gains from playing it.
This means that playing a crowd-pleasing record is not cool
. DJ:s want to be difficult
