This document evaluates the two music genres that apply to the song "Mr. Blue Sky" - art rock and pop rock. It discusses how art rock developed from 1960s rock and roll and was popular in the 1970s, making example music videos hard to find. For pop rock, it provides definitions and notes its popularity in the 1960s-1970s and 1990s-2000s. The document concludes that researching modern rock music video examples like "Fluorescent Adolescent" can help modernize the genres for a younger audience, despite taking elements from alternative and indie rock rather than the original genres.
