Sam Tsui and Casey Breves pair up for an unbelievable mashup of Ed Sheeran’s ‘Thinking Out Loud’ and Sam Smith’s ‘I’m Not The Only One.’ Sheeran and Smith are two of the hottest artists out their today, this is almost a dream mashup, really. Way to go boys! Hopefully I just made your Monday a little more enjoyable. Damn this is good. You’re welcome.
