The Evolution of Popular Music By Year (1950-2010) (U.S.A.) (Source: Billboard "Hot 100")

Another music history video, this time exploring Billboard's source. I won't comment on the video itself, since its quite similar to the previous one, using Musicoufitters as a source.

However, any conclusion drawn from the Musicoutfitters video is to be taken with a grain of salt, as it only gathers one source.

Right now I ham finishing the most complete and well sourced video. I will save any comments to when I post it.
