The reference to reverb is amusing -- in the early 1970s I recall
WCKY as an easy-listening station -- with reverb!

WJIB 740 AM Stereo in Cambridge/Boston, MA -- one of the few, if not
the last, Easy Listening/Beautiful Music stations on the AM band in
the USA -- uses stereo reverb. It's not too heavy, but you can notice
it.

That's only the *second* most inappropriate use of reverb I've ever
heard -- the most inappropriate was when KPRC in Houston
was a news/talk station in head-on competition with KTRH -- and
used reverb in 1985 and part of 1986!

FM talk station "New Jersey 101.5" (WKXW-FM Trenton, NJ) uses a
healthy dose of stereo reverb during their talk programming as well as
the Oldies music they play on weekends. It does get a bit annoying,
especially if you're listening with headphones.
