A fight song is a song often used by a sports team and its supporters to encourage the team to perform at its best.
Examples of a few NFL teams that have adopted a fight song are the Baltimore Ravens and the Chicago Bears. The fight song of the former is titled 'Ravens Fight Song' and that of the latter is titled 'Bear Down, Chicago Bears.'
The Philadelphia Eagles fight song 'Fly, Eagles, Fly' cannot be ignored as well. This fight song is especially noteworthy as it was sung during Super Bowl 57 when the Philadephia Eagles faced off against the Kansas City Chiefs.
Fight songs foster a sense of unity among the team and its fans.
