The Importance of SoundScan in Music History

In Hit Parade’s “Def Jams Edition,” we told you about rap’s first wave in the ’80s.

It would take Billboard rebooting its charts in 1991 tallying

record sales more accurately than ever with SoundScan data—for rap to get a fair shake on the charts. That boosted a new wave of crossover acts, from P.M. Dawn to Arrested Development to Sir Mix-a-Lot. But rap’s elders were not entirely thrilled at these new chart-toppers…and some rappers literally bum-rushed the show.
