Flip music

Flip Music is a type of music trend created and performed by humans.

Background
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 and others.

Trivia

 * Sergeant Major Johnson and an unknown number of ODSTs seem to be the only ones who enjoy this genre.
 * The flip music in the "Jenkins helmet cam" cinematic is a song from Marathon: Durandal.
 * It is strange that Corporal Locklear does not enjoy the beat of flip music, since it does match his personality quite well.
