We know that Thanos is the bad guy, but this pairing of song and subject turns the whole thing in to a fun experience, and makes you root for Thanos as he has himself a real good time.
But the lyrics of “Don’t Stop Me Now” and the editing of this video match the two up nearly perfectly for a fun look at Thanos’ hero’s journey.
Given the gravity of Thanos’ arc in Avengers: Infinity War you might not think that such an upbeat Queen song would work for the character.
