Is BTS The Biggest Band In The World?

But this wasn't the Beatles. It was BTS -- a seven-man South Korean mega-group which is quite possibly the biggest boy band in the world right now. In April, BTS became only the third group in 50 years to have three number one albums on the Billboard 200 charts in less than 12 months, joining the ranks of The Beatles and The Monkees. The next month, BTS became the first group in Billboard history to spend five weeks at number one on the Billboard Artist 100 chart.
