"An anthem is a musical composition of celebration, usually used as a symbol for a distinct group, particularly the national anthems of countries."
"Anthem is derived from the Greek ἀντίφωνα (antíphōna) via Old English antefn. Both words originally referred to antiphons, a call-and-response style of singing."
"The word "anthem" is commonly used to describe any celebratory song or composition for a distinct group, as in national anthems. Many pop songs are used as sports anthems, notably including Queen's "We Are the Champions" and "We Will Rock You", and some sporting events have their own anthems, most notably including UEFA Champions League. Further, some songs are artistically styled as anthems, whether or not they are used as such, including Marilyn Manson's "Irresponsible Hate Anthem", Silverchair's "Anthem for the Year 2000", and Toto's "Child's Anthem"."
