Drake surprise mixtape If You're Reading This It's Too Late tops Billboard 200 chart

Drake just might be the smartest rapper on the planet.

Just days after releasing If You're Reading This It's Too Late, the star's surprise new album has skyrocketed to the top of the Billboard charts.

The 17-track project, which features collaborations with Lil Wayne, Travi$ Scott, and PartyNextDoor, has earned the hip hop star his fourth number one album. His previous releases Thank Me Later (2010), Take Care (2011) and Nothing Was The Same (2013) also debuted at the top spot.

Since its unveiling on Twitter the day before Valentine's Day, the album has received rave reviews from fans and shifted almost 500,000 units. Pretty impressive considering it arrived without any warning or promotion.

The 28-year-old former actor is also celebrating another feat after making Spotify history. According to the music service, the record was streamed more than 17.3 million times in three days, giving it the most streams from an album in its debut week in the US.

If You're Reading This You're Too Late is the follow up to his 2013 album Nothing Was The Same, which spawned hits including Started From The Bottom and Hold On, We're Going Home.

In July 2014, he announced that his next album would be titled Views From The 6, but it has yet to materialise. The surprise release of If You're Reading This It's Too Late could be his way of drumming up publicity for the highly-anticipated record.

Although the Young Money artist's new music is available on iTunes and Spotify, a physical release for the album on CD or vinyl has not been announced.
