zu etwas aufgelegt sein
A fun look at the meanings of "auflegen" and what dj-ing has to do with making phone calls and newspapers.
The core idea of this root was:
laying, lying down
of course the verbs to lay and to lie belong here, but the root is also the origin of law, lair, ledger, allay and low. And of lager, which is essentially a German word that means storage.
