“Mmm Mmm Mmm Mmm” by Crash Test Dummies
If you thought a song just saying how blue they are over and over again, how this one? A song that just makes the “mmm” noise over and over so much so that it is the title of the song: “Mmm Mmm Mmm Mmm,” by the Crash Test Dummies. It ended up reaching the top 5 of the Billboard Hot 100 in 1993.
