After the huge success of "I Got a Boy" last year, Girls' Generation are back with their newest album, "Mr.Mr." which was released alongside 2NE1's album release - only days apart. Both girl groups are attracting massive attention not only in South Korea, but internationally with their comeback. Dubbed as two of the most popular K-Pop acts, fans are curious to who will come out as number one.

It was the song  "Mr.Mr." that caught the attention of David and his friend Dean, to which they decided to make an acoustic cover of - titled "Future Mrs." to make the song more fitting for a guy. Their cover was very fresh and relaxing to hear as both gentlemen's voices perfectly blended each other - the harmonization was also astonishing.
