The Most Clever Mash-up

I heard this song recently. It takes the top 25 songs of last year (based on Billboard) and puts them together. What an incredible talent - whether or not you like the songs. They must hear things differently - like a composer of a symphony - able to put a number of instruments together.

Here are the songs within the track:
The Black Eyed Peas - BOOM BOOM POW
Lady Gaga - POKER FACE
Lady Gaga Featuring Colby O’Donis - JUST DANCE
The Black Eyed Peas - I GOTTA FEELING
Taylor Swift - LOVE STORY
Flo Rida - RIGHT ROUND
Jason Mraz - I’M YOURS
Beyonce - SINGLE LADIES (PUT A RING ON IT)
Kanye West - HEARTLESS
The All-American Rejects - GIVES YOU HELL
Taylor Swift - YOU BELONG WITH ME
T.I. Featuring Justin Timberlake - DEAD AND GONE
The Fray - YOU FOUND ME
Kings Of Leon - USE SOMEBODY
Keri Hilson Featuring Kanye West & Ne-Yo - KNOCK YOU DOWN
Jamie Foxx Featuring T-Pain - BLAME IT
Pitbull - I KNOW YOU WANT ME (CALLE OCHO)
T.I. Featuring Rihanna - LIVE YOUR LIFE
Soulja Boy Tell ‘em Featuring Sammie - KISS ME THRU THE PHONE
Jay Sean Featuring Lil Wayne - DOWN
Miley Cyrus - THE CLIMB
Drake - BEST I EVER HAD
Kelly Clarkson - MY LIFE WOULD SUCK WITHOUT YOU
Beyonce - HALO
Katy Perry - HOT N COLD
