The Residents - Commercial Album (1980)

From their wikipedia page (which you should read if you aren't familiar):

The Commercial Album (1980) consisted of 40 songs that, like Eskimo, rejected traditional song structure. Each consisted of a verse and a chorus and lasted one minute. The songs pastiched the advertising jingle although the songs were not endorsements of known products or services. The liner notes state that songs should be repeated three times in a row to form a pop song. With a leap of promotional imagination, The Residents purchased 40 one-minute advertising slots on San Francisco's most popular Top-40 radio station KFRC forcing the station to play each track of their album over three days. This prompted an editorial in Billboard magazine questioning whether the act was art or advertising.
