It’s a well-known conundrum in the rules and regulations of the rock’n’roll canon: If it is popular, it must not be good. While AC/DC has millions of fans the world over and can continue to sell out arena tours (even with a completely different and controversial lead singer), they have very few critical accolades to show for it. They’ve won only one Grammy – for a song released in 2010, no less – and even the likes of Billy Joel managed to beat them into the Rock’n’Roll Hall of Fame.
