The Rock & Roll Hall of Fame notes on their website that "the top five artists, as selected by the public, will comprise a 'fans' ballot' that will be tallied along with the other ballots to choose the 2019 inductee." For an artist to be eligible, they must have released their first single or album at least 25 years before the year they are nominated.
The impressive members of The Hall currently includes bands/artists across a variety of genres, including Aretha Franklin, Elvis Presley, Johnny Cash, KISS, David Bowie, ABBA, Billy Joel, Fleetwood Mac, Aerosmith and the Eagles.
