whalecore 

A genre used to describe Mastodon's 2004 concept album, Leviathan, which is based on the story of Moby Dick.

Frustrated that they were unable to fit the album into existing genres, fans of the band coined the term to point out the inherent humor in dedicating a full-length metal album to the topic of a whale. The album can be most accurately described as a mix of heavy metal, metalcore, and progressive metal.

whalecore:
Split your lungs with blood and thunder
When you see the white whale
Break your backs and crack your oars, men
If you wish to prevail

Half whale, for being rare. Half unicorn, for being magical.

whalecore 

A "genre" of music used to describe bands with at least one album in which the cover artwork displays a whale. This is a popular tag used amongst music sites such as last.fm.

Albums that fit this description:
"Leviathan" by Mastodon
"From Mars to Sirius" by Gojira
"The Call of the Wretched Sea" by Ahab

When they couldn't find an accurate classification for Mastodon's "Leviathan", fans took hold of the cover art and thus defined it as whalecore.
