My mom does! We used to go online each week and see who's hot and who it's not. that was back in... 2007-08? I was in middle school and my mom and I were obsessed with music videos, we'd watch VH1 Top 20 Countdown on the weekends non stop!
My Uncle knows about it, and my Mom knows somewhat about the Charts because I told her how they come up with the winners at Billboard Awards and when we talk on Music I'll discuss how they're performing.
