Although it has yet to crack the Billboard K-pop top 40, "Waiting," released earlier this month by singer Andamiro and featuring rapper Double K, is undoubtedly worth a listen.

The song begins with a hauntingly beautiful melody. And before the beat even drops, the producer makes the unexpected choice of having Double K rhyme over the stark backdrop of an acoustic guitar.

"Waiting" isn't even a song that would even typically feature a rapper.

There is nothing in the rhythmic or musical accompaniment that would suggest an MC's services are needed.

Yet Double K rises to the occasion.

The rapper, who is part of the collective The Movement Soul, busts a flow that is original and works surprisingly well with the track.

His angry words that are basically a tell-off to Andamiro's "Waiting" protagonist make the singer's vocal performance all the more heartbreaking.

Andamiro, whose real name is Won Min Ji, debuted last year on Trophy Entertainment.

The fact the label isn't exactly one of the entertainment forces in K-pop has been blamed for the singer's ability to earn major chart success.

But the singer has a voice that stands out from the rest.

In "Waiting" Andamiro floats between ethereal exhalation and high-energy exaltation, nailing both with equal poise and ease.

She also has an impressive emotional range. Her music video from last year "Hypnotize" which featured Andamiro as a sexy maid, was taking her into Lady Gaga territory.

The performance on "Waiting" is something completely different, demonstrating an emotional depth that is would be hard to know even existed within the same artist from watching the "Hypnotize" video.

The powerfully stripped down performance on "Waiting" is a much better vehicle to demonstrate the depth of Andamiro's talent.

One striking aspect of the singer's performance on "Waiting" is the beautiful way her phrasing changes when she alternates between English and Korean.

When many K-pop artists throw in English words into their songs it can be confusing or even cringe inducing.

Yet with "Waiting" it is quite different.

The most moving moments of the song are the parts where the entire musical accompaniment strips away and all that is left is Andamiro singing the line "I'm waiting for you."

There is something surprising affecting about that moment.
