I remember putting together mix tapes for my own imaginary radio station - WJAM - when I was a child,

When Paul and I got together, it was an opportunity to mix it all up.

I remember that in Baltimore, where I grew up, we would drive by the radio station and tower of WBAL, and I would try to picture the people inside and what they did there.

I've shaken hands with every radio station, from Honduras to Ryan Seacrest's.

I am putting real plums into an imaginary cake.

An analogy would be when you're scanning the radio dial and you get the same station separated by a small blank space. The size of the blank space is directly proportional to the strength of the magnetic field at the location in space where the station is being broadcast.
