If you're a fan of The Voice on NBC then you probably heard this track live.  Christina Aguilera teamed up with A Great Big World to sing their track 'Say Something'.

The official music video first premiered on the closing credits of Entertainment Tonight.

I was first introduced to this song by my six foot three, country-loving, body builder friend as his favorite song.  (Ironic I know)

It has quickly became one of my favorites as well.
