Why Even Have a Fan Vote for Rock Hall of Fame?

@Perfume-shroom92 Rock and Roll Hall of Fame. For the biggest acts in Rock and Roll.
Donovan and U2 are in it as well as The Beatles, the Stones and many other acts from your side of the pond. Kinks, Who, Dave Clark 5, Pink Floyd, Moody Blues, Clapton, Led Zeppelin, etc. They induct new acts each year from influential rock artists who have been active for at least 25 years. They started having a fan vote several years back and are supposed to give the fans a say in who they think are worthy artists.
