Cyndi will obviously be more remembered than Madonna, at least by this generation. Most of their sales came from before this generation so we can't look at that, however the youth are streaming/listening to Girls Just Wanna Have Fun and Time After Time way more than Madonna's 80s/90s hits
You can't even get her name right when you're trying to defend her and she will be a legend?
Why did I laugh?
Anyway, at least V magazine acknowledges Kitty is always second best, the bridesmaid never the bride. The Billboard award winner, never the Grammy winner... Neither a diamond chanteuse.
Not a Bad Thing is the only song to go Top 8 this decade and not sell more than 90k in atleast one week. Excluding "Dope" & "Gangnam Style" -- Streaming fueled smashes.
Which means it's the biggest case of radio payola this decade.
