Hip-hop history often works out to an entanglement of stories and samples, and the origin of Drake’s infamous “6” drop is no exception if a recent experiment holds true.

Konner Wilson, an Ohio recording artist, took it upon himself to do some research and conduct a quick A-B test that makes for some strong evidence. In a tweeted video posted earlier this afternoon, he alternates between a recording of Chuck D counting on Public Enemy’s 1991 song “Shut ‘Em Down” and the echoing “6” tag that’s become inseparable from Drake’s recent output. It’s strikingly similar when heard back to back (no pun intended).

Watch Wilson’s clip above, and head below to listen to Public Enemy’s “Shut ‘Em Down” and Biggie’s “Ten Crack Commandments,” which samples the same Chuck D line.
