A sad love story featuring the acting skills of A Pink's Na-Eun.

Ooh, ready to hear some smooth vocals? From a fashionista's standpoint (or at least I would like to think I'm one haha), the different outfit changes work well with the colorful scenes and props. It's a cute and fun one!

These two child actors will make you feel some type of way, and it's matched perfectly with 'K-pop Star Season 2' finalist, Shin Ji Hoon's heartfelt vocals.

After Rain was discharged from his military service, he signed with Cube, and this movie-like music video was born.

This song was refreshing when it came out, but still unique to the sound of K-pop. Plus, their dancing is on point.

When you put HyunA and Hyunseung together, it gets steamy and the chemistry is unreal!

This is the A Pink that we've all come to adore.

This was my summer jam in 2013. We get to see the girls of 4minute really shine in this comeback, and it resembled their debut days of 'Hot Issue' back in 2009.

Who doesn't love a Korean drama condensed into 7 minutes? I can't help but to smile when watching this music video.

If you like intensity, watch this well made mini-movie. By the way, I love how Cube artists' cameo in each other's music videos.

Bubble bubble bubble pop, bubble bubble pop pop~!

Hands down, this is her best song and one of my all-time K-pop favorites. It also makes a perfect break-up song.

I fan girled soooooo hard when 4minute came out with this. It's high in energy and slays in every way possible.

Such a poetic and sad song. This is one of the best of BEAST, and check out that footwork.

Ladies and gentlemen, this right here is one of the songs that made up the glory k-pop days of 2009.
