If you want to be one of the most streamed artists on the planet, there's one thing in particular that you apparently need. That thing is a penis.

Every holiday season, Spotify releases its end-of-year stats, and we get to have a good look at both our own music habits with personalised top tracks-lists, and the lack of gender diversity in the music industry at large.

Spotify just released the most-streamed artists list and yeah, they're all dudes. The most streamed artist is Drake, thanks to his Scorpion album, followed by Post Malone, and late rapper XXXTentacion. Number four is Columbian singer J Balvin and last on the top five is last year's most played artist, Ed Sheeran.

The exact same thing was the case in 2017, where the top five artists were also all male.

No women are to be found in the most-streamed groups category either. The top five groups are Imagine Dragons, BTS, Maroon 5, Migos, and good old Coldplay, last year's most streamed group.

In a separate category, most-streamed female artists has Ariana Grande at the top, followed by Dua Lipa, Cardi B, Taylor Swift and Camila Cabello.

The music industry has grim numbers when it comes to gender equality. An analysis reported on by the New York Times looked at the top 600 songs from 2012 to 2017, and found that of 1,239 performing artists, 22.4 percent were women. The numbers are even lower for songwriters, 12.3 of whom were women in the measured period.

Similar issues caused a backlash against the Recording Academy at this year's Grammy Awards, where the social media campaign #GrammysSoMale highlighted the fact that only one woman (Alessia Cara) won a major award, even though the most nominated artist was female (SZA.)

The backlash prompted Recording Academy president Neil Portnow to say that women in the industry just need to "step up."
