The acronym "A&R" is unfamiliar to me in radio parlance.

Would someone shed some light?

Artistry & Repertoire, the department (and guys) who sign new acts, and
sometimes find stuff for them to perform - though that was more in the earlier
days than now.

I recommend the novel "A&R" but I can't locate the name of the author right
now. Good insight into that end of the recording industry.
