With sales of Adele's "Hello" and 25 considered, the singer is 2015's undisputed success story. But where streaming's concerned, this year is all about the gentlemen.

Spotify has released its year-end rankings of the most-streamed artists, and according to Music Week, the top three spots belong—in descending order—to Drake, Ed Sheeran and The Weeknd. Maroon 5 and Kanye West are No. 4 and No. 5, respectively. 

Drake managed to attract 1.8 billion streams and amassed 56 million listeners, effectively dethroning 2014 Spotify King Sheeran, who notched 860 million streams last year, according to Entertainment WeeklyDrake was also the top performer in the United States market.

And though fans are still waiting for Anti to drop, Rihanna was the service's top-streamed female artist globally, beating out—in order from No. 2 to No. 5—Ariana Grande, Nicki Minaj, Beyonce and Ellie Goulding. Strangely, though, Minaj and Beyonce outperformed Rihanna at a domestic level.

Where singles are concerned, Major Lazer's "Lean On," the Felix Jaehn remix of OMI's "Cheerleader" and Mark Ronson's "Uptown" Funk were the most streamed tracks worldwide, while The Weeknd's Beauty Behind The Madness, If You're Reading This It's Too Late by Drake and Major Lazer's Peace Is The Mission were the Top 3 albums.

A final point of note: Justin Bieber set a record for single-day streams—he drew 36 million listens on November 13, the day his Purpose was released.
