In 1978, a movie called "FM" was released.
It was a really good movie, although running on the cliché (yet true and sadly timeless) theme of a wildly successful radio station that gets interference from bean counting management, utterly clueless and indifferent to the people that made the station successful who expect their input to make the station even more successful. Which more often than not ends up trashing the station.
I'm not going to spoil it beyond that, but I would put this movie in my Netflix queue if I were you. FM was also the inspiration behind the legendary WKRP In Cincinnati.
FM also had one of the best soundtracks of any movie of the 1970s. It was a compilation loaded with original hits from the original artists on a two LP album set. In their full length album versions, not edited single versions (which besides FM radio's sound quality, the full versions of songs were also what made FM radio great in the 1970s.) And certainly not like a K-tel and Ronco record. The soundtrack was mastered by Gary Katz, the golden ears behind Steely Dan's classic '70s albums. It was truly one of the very best sounding soundtrack albums I have ever heard and MCA Records spared no expense in getting this right.
On the flipside, budget record label Pickwick Records tried to cash in on the popularity of FM's soundtrack with their typically crummy knockoff record of incredibly LOUSY cover versions of the FM soundtrack's hit songs.
....and I do mean lousy.
Listen to this hysterically bad cover of The Eagle's "Life In The Fast Lane"
