Check this mashup out. I'm a sucker for a good one. The similarities between these two songs were always there when I first heard them, but now that they're together, wow! These dudes mash up a bunch of different songs, but this is the best one they have so far. Kind of got me to thinking, what if Ed Sheeran and Sam Smith did team up for a duet? What would that sound like? Probably very similar to this. Check out the video.
