Data from Spotify confirms that the older you get, the less "with it" you are. Ajay Kalia, a data cruncher at the music streaming service, came up with the findings after he calculated a popularity score for all songs streamed in 2014, and then examined the age and gender of people who listened to them.

 Here's what Kalia found:

 Teens listen predominantly to popular music (no big surprise there), however this percentage of “musical relevancy” drops as they age into their 20s, and then stagnates once they reach their early 30s.

 Both men and women listen to the same amount of pop music in their tweens and teens, but soon after it dramatically decreases much faster for men than it does women.

 Kids are the quickest way to kill your cool.

One way to to say “forever young”? Don’t have kids. Having a child roughly ages your listening habits by about four years. Kalia found that parents of all ages listen to smaller amounts of popular music than the average listener.

Although if that’s a decision you really want to make, you could always wait until your toddler is a teenager again in order to be exposed to what’s hip again.
