The term used by everyone to define their favorite band on Urban Dictionary. Especially common among listeners of lesser-known bands and younger people with narrower tastes. It can never be known who the best band ever is, because it is subject to different preferences and opinions.
Teenage girl: GREEN DAY IS THE BEST BAND EVER!
Melodic death metal fan: Green day has no talent- you're just a conformist who likes to bandwagon on every hyped band with sex appeal. Clearly, Opeth is the best band ever.
Objective listener: Neither one of you is completely right- now please stop cluttering Urban Dictionary with your opinions!
