If we're already in 2021, then:

60 years ago, doo-wop was big:


55 years ago, the British Invasion was kicking:


50 years ago, soul was the biggest thing:


45 years ago, disco was the hottest new trend:


40 years ago, new wave was big:


35 years ago, freestyle was taking over:

20 years ago, nu-metal was huge:


15 years ago, emo was kicking:


10 years ago, dubstep was massive:


5 years ago, trap invaded everything:


And 1 year ago was finally behind us

It's crazy to think how much music has evolved in only 60 years. Makes you wonder how 2076 will sound like.

I can't believe that songs like Party Rock Anthem, Born This Way, and We Found Love are already 10 years old. I hate being older sometimes....

I think the milestone that blows me away the most is Nirvana's "Smells Like Teen Spirit" turning 30 years old next September. The '90s alt-rock scene still doesn't feel that old to me, and I can vividly remember as a kid when 1991 was only 15 or so years ago. 

2006 being 15 years ago is another milestone that hits me hard. I was 7 that year and it would have to be the first year that well and truly feels like yesterday for me.
