Mantis was a term used to describe a seemingly random genre of music. Mantis music is often seen a a renaming of the metal genre, seeing most of the songs that are classified as "mantis" have the exact same characteristics of metal songs. However, songs with a piano-focus (i.e. "Our House" by Madness, "100 Years" by Five for Fighting", "Allentown" by Billy Joel) are also considered mantis.

Etymology: David Schneider, a socialist revolutionary and film/music critic coined the term in 2005 to replace the term, "metal", which he felt sounded too lame in 21st-century society. It was derived from the insect, the praying mantis.
"I love Mantis albums. Going from a face-melting, guitar-shredding song into a catchy, smooth piano song is an experience like none other.
