Although Big does play familiar stuff to rock fans, "Classic Hits" is a kind of unofficial moniker for what used to be called "oldies" in radio jargon. With few exceptions, "classic hits" are songs that have appeared on 45's.
Big hits of the 60s & 70s, even mellow ones like "Love Is Blue" or "Love's Theme" would qualify for classic hits, but Big wouldn't touch those songs w/ a 10 ft. pole. A song would have to "rock" for Big to consider it.
That said, Majic has experimented with stuff that Big could play or has played.
I suppose it's mainly called "classic hits" to separate itself from true "oldies", which would include hits of the 50s & early 60s (basically pre-Beatles). Very few stations in the US still play the latter, although the 50s/60s board has a thread about it.
Anyone going through the Sebring area should turn on AM 1050---there's your oldies!
