thats actually a hard one. tony and clint are both pretty decent, and they can both play a couple instruments. thor can sing loudest, and he usually sings beyonce, and listening to Hulk hum is an experience, its like a very quiet subwoofer. nat generally only sings for humor reasons, but shes always on-key. steve cant sing at all. youd think that after the stage show hed have picked something up, but no. not even super soldier serum can cure tone deafness that strong.
i sing okay, but thats between me and my showerhead
