I'm not sure. It's a hard problem. There are, I hear, some very good sites for get youtube statistics, which could help find out what years songs have been popular on YT. I'm not sure how to do records, though. And ultimately, I'm partly basing this off of my childhood, which was out of the ordinary, music-wise, so you need a larger sample size.
