I tend to sometimes listen to the Top 40 countdown on the radio from time to time and I have also seen song countdowns on music channels in the past as well that are hosted by different song artists as well in the past.
They are a lot of fun to listen to and watch if you are interested in things like that.
When I was very young I used to tape all the songs that made the UK charts during the late 60s/early 70s. That for me will always be the golden era for chart topping music.
