Kendrick Lamar has his second No. 1 album in less than a year. After surprise-releasing his new LP Untitled Unmastered on March 4, the "Alright" rapper owned the charts this week, besting recent releases from 2 Chainz, Adele, Rihanna and more.

Untitled Unmastered, which was comprised of demos and outtakes from Lamar's Grammy-winning album To Pimp a Butterfly, moved 178,000 album units this week, Billboard reports. And despite the surprise release's availability on streaming platforms such as Spotify, the vast majority of Lamar's units came from sales - 142,000 total.

Lamar isn't the only rapper with a new release in the top five this week. 2 Chainz's ColleGrove, which heavily features Lil Wayne (on eight of the album's 12 tracks) landed at No. 4 this week with 53,000 units moved (34,000 of which are pure album sales). As of now, all of those sales were digital; the album is due for a physical release on March 25.

Between the new rap releases, Adele's 25 had another solid sales week with 61,000 units moved and a No. 2 landing position. She slightly leads Rihanna's ANTI, which holds at No. 3 for a second week with 58,000 units.

Justin Bieber's Purpose rounds out the top five for a second week, with 53,000 units.

Actually, beside the new releases from Lamar and 2 Chainz, the rest of the top 10 on the Billboard 200 are older releases. Joey+Rory's Hymns saw a four position and 35 percent increase in position this week following the death of Joey Feek on March 4. The Christian country duo's final record moved 44,000 copies.

The rest of the top 10 was relatively uneventful. Chris Stapleton's Traveller maintained its No. 7 position with 39,000 units; Twenty One Pilots' Blurryface also stays in place at No. 8 with 34,000 units. The Weeknd's Beauty Behind the Madness and Kevin Gates' Islah round out the top 10 at Nos. 9 and 10, respectively.
