Leave it to Sam Tsui to take three totally different pop hits, and seamlessly arrange a mashup between them all with the only common factor being that they all allude to explosions. This guy is too talented. Did you ever think Katy Perry’s “Firework”, Bruno Mars’ “Grenade” and Taio Cruz’s “Dynamite” could work as a single song? It never crossed my mind but I’m glad it now exists. Major props to Sam & company. Plus it’s a free DL!
