A solution to last week's challenge can be found here!
Nothing makes you feel quite as nostalgic as hearing a song you haven't heard in a while. That's probably why Billboard magazine has been publishing their "Hot 100" list since 1958. If you aren't familiar, the "Hot 100" list ranks the top 100 singles in the US each year. It can be pretty fun to read through, but let's take a look at who dominated the decades.
This challenge's dataset includes rankings from 1965-2015. Determine which artist(s) created the most top 100 hits in each decade. Then, try the same but with top 10 rankings.
