There were exactly 16 rap songs released in 1979. Can we do a best rap song from 1979 tournament?
Here's a link to Ego Trip's Book of Rap Lists, they list 15 rap songs from that year
^^^In addition to those 15 songs, Eddie Cheba also released a song that year (which was a dud).
16. Lookin' Good (Shake Your Body) - Eddie Cheba
Anyway, its just an idea.
In case you're wondering I have all the songs on mp3 and could post them if you'd like. And for the record, my favorite songs from that year are; Rapper's Delight, Superrappin, Rappin and Rockin The House and Christmas Rappin. You should set it up so those songs would face each other in the final four.
