Albums sales were led by EXO. EXO was a relatively quiet and weak brand in the previous year, but they came back kicking for 2013.

Their singles "Growl" and "Wolf" were the runaway hits that drove the album sales. The repackaged version of their first album XOXO that included "Growl" sold 310,000 albums for the top album sales of the year. The original first album that had the song "Wolf" sold 250,000 albums. The "HUG" version of XOXO sold 190,000 albums, and the repackaged "HUG" version of XOXO sold 180,000 albums. All in all, EXO's first full album sold 950,000 albums.

Girls' Generation was not far behind. Their 4th album I Got A Boy released in early in January, sold for 290,000 for the second place. Their title song of the same name was the 10th most download track. Girls Generation also showed their international fame, as the song was listed at #5 for the "Song of the Year" on Time Magazine's annual list.

Jo Young Pil's 19th album HELLO sold 250,000 albums, while G-Dragon sold 190,000 albums with his album Coup D'état.

SHINee's third album Dream Girl sold 180,000 albums, which makes it the 8th most sold album of the year. Infinite's 2013 albums, Destiny and New Challenge, each sold 160,000 for the 9th and 10th most sold album of the year.

When it comes to music videos, however, no one beat out PSY. It's not hard to see why - his video for "Gentleman" is nearing 600 million views on YouTube. Although the music video was deemed too obscene in Korea, Time Magazine voted it the most viral music video of the year.

Girls Generation's music video for "I Got A Boy" was a distant second place in terms of views. It received 78 million views on YouTube, making them the only Korean idol group that ever got close to a 100 million views on YouTube. This video was nominated by YouTube as the music video of the year.

EXO's music video for "Growl" and "Wolf" had the next most views at 20 million and 18 million respectively. The music video for "Growl" was praised for its unique filming technique.

The next six groups were basically in the same tier, since they all received a similar amount of views. f(x)'s "Rum Pum Pum Pum" is the 5th most viewed music video, and is followed by 2NE1's "Falling in Love", 4MINUTE's "What's Your Name", G-Dragon's "Crooked", Trouble Maker's "NOW", and Taeyang's "Ringa Linga (Dance Version)."
