YG Entertainment's newest artist Akdong Musician (aka AKMU) explodes onto the charts this week with their first studio album Play. All 11 tracks from the album have debuted in the top twenty, with lead single "200%" taking the top spot at No. 1.

"200%" is actually the duo's third No. 1 to date, following "You're Attractive" and "Crescendo" which topped the charts back when AKMU were contestants on the reality TV competition K-pop Star, which is where they got discovered.

Squeezing in at No. 2 this week is rookie boy band HIGH4 with their first single "Not Spring, Love, Or Cherry Blossoms." The song features K-pop princess IU, which is definitely a large reason why it's done so well. Also, the fact that it's a seasonal tune tailored to spring certainly helps too.

A Pink's "Mr. Chu" is still going strong despite falling to No. 7, while Orange Caramel's "Catallena" finally budges from No. 6 where it's been stuck since it was release, slipping down to No. 19. (You can 'thank' AKMU for making "Catallena" fall so far!)

Crayon Pop's "UH-EE!" is down to No. 24, followed by 4minute's "Whatcha Doin' Today" at No. 25.

Meanwhile, Jay Park manages to scrape into the top thirty with his new single "Metronome," which debuts at No. 28. The song features Simon D, who is also co-CEO of Jay's new independent hip-hop label AOMG. "Metronome" is their first release through AOMG, so hopefully they're happy with how the song's done.

Further down, Eric Nam debuts at No. 57 with his single "Ooh Ooh" featuring INFINITE's Hoya. Some of you might recognize the Korean-American singer from his popular Youtube covers, but it looks like from now on you'll have to find him on the charts instead!

No. 1. AKMU - 200%

No. 2. HIGH4 feat. IU - Not Spring, Love, Or Cherry Blossoms

No. 28. Jay Park feat. Simon D and Gray - Metronome

No. 57. Eric Nam feat. Hoya - Ooh Ooh

A Great Big World's "Say Something" became one of the surprise sleeper hits of last year after a co-sign and remix from Christina Aguilera catapulted it into the spotlight and straight to the top of the iTunes chart.

With the song still going strong, Korean singer and Youtube star Eric Nam has teamed up with Boa from rising K-pop girl group SPICA to record a special viral cover of the indie ballad.

We don't really wanna piss off any Great Big World fanboys or Xtina stans by saying that Eric Nam and Boa's cover is better, so we'll just say that we enjoyed them both equally -- even if deep down we really didn't!
