As mentioned numerous times already, the 1960s are the most critically acclaimed decade ever when it comes to music. Or, in other words:

THE SIXTIES ARE THE HOLY GRAIL IN TERMS OF MUSIC QUALITY.

This is the music you need to know if you want to become a great artist, no matter what genre you’re doing nowadays. This is the music you need to compare your own work to, if you want to improve it.

• ABOUT 40% OF ALL OF THE GREATEST SONGS OF ALL TIME WERE WRITTEN IN THE SIXTIESWhich makes up about 50% of the best songs written in the Golden Age Of Popular Music.
• MORE THAN 250 SO-CALLED “EVERGREENS” WERE RECORDED IN THAT DECADE ALONE.Those are songs that everyone knows or should know, and that humanity will probably never forget. 
• THAT’S ONE EVERGREEN EVERY TWO WEEKS!At least two incredibly great songs we all still know today had been released each and every month in that decade.

That’s just insane, and those numbers alone clearly show how far we have come with today’s music.
