The station was known for playing pop tunes reworked in the form of instrumentals. At first, it played two vocalists per hour, although over time, more vocals were added. The instrumental music was based on the works of such artists as Frank Sinatra, Tony Bennett, Nat King Cole, Neil Diamond, The Carpenters as well as songs from movies and Broadway. By the 1980s, the station increased the number of vocals to four per hour, either from the middle of the road format or from the soft adult contemporary format.
