For decades, everybody in the music business knew one thing for certain: if you wanted to break a new artist, you had to get their songs played on the radio. Radio DJs were the gatekeepers of the industry, offering up-and-coming acts a level of exposure that could change their careers almost overnight. Acts like Jay-Z and REM — among the most successful of the ‘80s and ‘90s — got their starts by forging powerful alliances with regional radio stations before ascending to national stardom.

But with the advent of streaming services, times have changed. Spotify, Apple Music and other platforms are leveling the playing field, allowing unknown artists to bypass radio and still build massive, global fanbases. The editors of curated playlists on Spotify and Apple are suddenly supplanting radio DJs as (arguably) the industry’s most influential tastemakers.

Music industry veteran Bob Lefsetz noted this shift in a 2017 edition of his newsletter. Here’s what he had to say about the current dynamics between streaming and radio:

By waiting so long to go on tracks and sticking with them radio is clogging the arteries, and signing its own death warrant. Who in hell is gonna tune in to hear that which was a hit months before? NOBODY! Radio is almost like reruns. -Bob Lefsetz

But just how accurate is Lefsetz’s assessment? Is radio really losing its standing as a purveyor of new music and emerging trends?

To find out, we grabbed data on every song that broke either the top 50 on Spotify or radio (according to Billboard) dating back to the week of December 29, 2016. Our analysis lends insight into how quickly new songs are finding an audience through streaming vs. radio and how that differs by genre.
