When thinking back on the music of the ‘90s, iconic names like Britney Spears, NSYNC and the Backstreet Boys probably come to mind. Back then, you could count on stations like MTV to find your favorite music videos playing every morning, or turn on TRL for appearances by your favorite bands. While pop music certainly defined much of the decade, it definitely wasn’t the only powerhouse genre around—other major rock and R&B artists dominated the scene, from Blink-182 to Destiny’s Child and beyond.
