Katy Perry and One Direction also become world record holders
The 2015 edition of the tome, which is released next week (September 11), also features other new additions including Katy Perry, One Direction and Shakira.
As Billboard reports, Metallica’s inclusion is for their feat of becoming the only band to ever perform gigs on all seven of the Earth’s continents in one year. They crowned the achievement with their gig in Antarctica last December.
Miley Cyrus, meanwhile, now holds the world record for being the most searched-for pop star on the internet, partly due to the buzz she generated after her controversial performance at last year’s MTV VMAs and the video for her single ‘Wrecking Ball’. Eminem’s ‘Rap God’ is also recognised as being the hit single which contains the most words – it totals 1,560 words in its six minutes and four seconds running time.
Other new entries include Shakira, who became the first person to reach 100 million ‘likes’ on Facebook; Katy Perry, who has the most Twitter followers (52, 463, 838); and One Direction, who are the first act to debut at Number One with their first three studio albums. Their LPs ‘Midnight Memories’, ‘Up All Night’ and ‘Take Me Home’ all took top spot on the US Billboard charts.
