Re: Great AM pop tunes
Back at the time when I was a teen, FM radio was primarily new and was playing classical music. AM radio was playing popular top ten music when a lot of commercials and upbeat disk jockeys all trying to make a name for themselves, and most of them usually had some sort of act or schtick to define their personalities. FM radio was more high brow, more mature music and programming. I hope that helps with the term AM pOp Music.
