Flip music

Flip Music is a type of music trend created and performed by humans. The colonial "slam-bam" beat of flip music is, in fact, a descendant of 21st-century heavy metal. Sergeant Major Avery Johnson has an odd fascination with the genre. Those around him, however, are less interested in this genre of music. There are many who dislike flip music, including Captain Jacob Keyes, John-117, Corporal Locklear, Private First Class Wallace Jenkins, Privates Riley, Mendoza, Bisenti, etc.

Trivia

 * Sergeant Major Johnson and an unknown number of ODSTs seem to be the only ones who enjoy this genre.
