There's a new video floating around online of singers Sam Tsui and Casey Breves singing a mix of Ed's "Thinking Out Loud" and Sam's "I'm Not The Only One". In the, the two guys each take on one of the songs at the same time, and the mashup together sounds freaking amazing.
This clip totally reminds us of the Taylor Swift "Blank Space" and "Style" mashup that artists Louisa Wendorff and Devin Dawson made a few months ago. Even Taylor tweeted about that one.
Check out the guys' Ed and Sam mashup video below. Love it?
