It is impossible to classify Lim Kim.

There is nothing anything else like her music on the K-pop charts.

With a voice like something out of a dream and a music backdrop that even when it is at its most laid back, she seems to always be enthralling.

With "Rain," Lim Kim, aka Kim Ye Rim of Two Months, teams up with a tasteful jazz quartet and with an obvious nod to Norah Jones, delivers a haunting jazz ballad that still swings.

There are plenty of female balladeers in the South Korean music scene pouring their heart into songs that either null you to sleep or jar you with melodramatic theatrics.

But there is something so original, so pure about Kim's talent that makes all of her music stand out and stay in your mind.

Whether it's the rich guitar orchestration of her Radiohead influenced track "Like You Know It All" or the spooky dance music of "All Right," to listen to a Lim Kim track is to fall under its spell.

Why is Kim Ye Rim different from the endless parade of performers trying to engage their fans with the depth of their emotional feeling?

Perhaps it is that the singer employs the opposite approach.

There is a detached quality to Lim Kim's performances that many of the greatest vocalists, particularly in rock have employed; you shouldn't care so much.

There will always be a certain type of listener, millions of them in fact, who relishes a Celine Dion over-the-top pop ballad.

But for the rest of us, there is something intriguing about an artist who instead of communicating just how broken up she is over a break up, dials in some different emotions, feeling and sounds.

And she often errs on the side of haunting sounds.

Lim Kim songs sound like they should be played through a crackly old AM radio. There is something timeless about them, an effect that is in no small part due to the well-crafted songwriting.

If you somehow found yourself standing in a haunted house and a Lim Kim song came pouring out of a speaker in the room, not only would it seem like a pitch perfect eerie soundtrack for that particular moment, but you may also find it difficult to run out the door.

"Rain" debuted this week at number seven on the Billboard K-Pop Hot 100.
