Some songs stay in our hearts for decades.Matt Daniels, a data scientist and editor of Polygraph, discovered exactly which songs are timeless by combing through mounds of Spotify data.
He looked at the streaming service's catalog of '90s songs and then ranked them by their play count in 2014 (the most recent year available).
The data includes people of all ages, but skews young considering the majority of Spotify users are in their 20s.
As he points out, until recently it was impossible to quantify the popularity of older music. But now, Spotify collects a vast amount of data about the bands we crave and how many times we play them. Daniels collaborated with Spotify to collect and analyze all of that data.
Here are the top '90s songs that fans still spin on repeat, according to his research.
10. Whitney Houston — "I Will Always Love You"
Play count: 27.48 million
9. Radiohead — "Creep"
Play count: 28.93 million
