I feel you Chaz on P-Rock as well as Looking for the Perfect Beat but for me, it was 1980 and Rapper's Delight. First real exposure and Grandmaster Flash & Furious 5 all through HS. Man, we would moonwalk to class in between periods. it was crazy. You'd be sitting in class and someone would moonwalk or poplock past your door on the way to the bathroom. The class would be rolling! but yeah, Rapper's Delight launch it for me and the whole school had a daily contest to see who could be the first to recite the lyrics all the way through without messing up. We did this everyday at lunch. If you messed up a verse, you were done for the day. Come back tomorrow. It was insane. "The Breaks" & "Freedom" were the skating rink joints and the honeys pack the floor when they came on. But I remember Planet Rock being like the no. 1 joint on the Detroit radio countdown all summer in 82'. It was the best of times.
