Led Zeppelin

With more than 138 million certified sales, Led Zeppelin are the sixth best-selling artists of all-time, behind only The Beatles, Elvis, Michael Jackson, Madonna, and Elton John. They’re often credited with the birth of heavy metal, and their unique combination of blues with a heavy psychedelic element certainly gave them a distinctive sound.

The band’s fourth album, generally considered their greatest and one of the best in the history of rock music, contained the legendary single Stairway To Heaven. That song stands today as the most requested song in the history of American radio, and the eight minute classic nearly always appears in lists of the greatest songs of all-time. Yet it wasn’t even the closest the band came to a number one hit. That honor goes to the equally great Whole Lotta Love, which reached number four in December of 1969.
