And then there was WMGK, playing only soft cuts from Rock albums. It wasn't AC. They didn't play artists who were only popular on Top 40 like the Carpenters. They had to be heard on Rock stations. I believe they used the syndicated music service from TM called "Beautiful Rock" even though they never said that on the air. It also aired on co-owned 98.3 WMGQ New Brunswick NJ. If you were in a place that got both stations, they often were playing the same song at nearly the same time.
WMGK in Philly was the originator of the "Magic" format. It was designed by the late, great Julian Breen and executed by the late, great Dave Klahr. Basically, it was a format that contained any song from any genre that fit the overall soft sound. Nothing too jarring or harsh, so when the hard-rock KISS put out s soft song like "Beth", it fit right into MGK's format. Generally, it featured a lot of folk music tracks, along with more pop stuff by America, Judy Collins, Neil Diamond.
The format in those early days was done on 5x7 cards. Three songs out of four were typed onto a card which had a "set number". The fourth song would be the DJ's choice from among the current songs that were in play, as long as the sex and tempo fit the blank space on the format card, and keeping in mind the last time that current was played.
Commercials had padded-down levels, so they were all but unheard in a public setting. I recall sitting in a noisy downtown H.A.Winston restaurant with WMGK on their music system. The music disappeared after the last song in a set, and you heard nothing over the restaurant din until the jingle kicked in to start the next set. The jingles were always the loudest thing on the station, cutting through everything, then the music levels were slightly lower, and the commercials were almost non-existent. Harsh commercials were never accepted and business was frequently turned away. Imagine THAT today!
The set numbers were predetermined each day and each hour had four sets. Those set numbers were then sent to the other "Magic" stations, generally to play exactly a week later. The "Magic" format at the time aired in New Jersey, Detroit, Portland, ME, and I believe Long Island. That format ran from the earliest days in 1975 through to around 1980 when Bob Craig arrived to take the station in a more pop direction.
Ah - radio when it was still fun, challenging, and adventurous - nearly forty years ago.
