A fascinating video from one of the best Youtube channels around. Personally there are two pieces of music from Marvel movies that are quite catchy. One is The Avengers Theme, and the other is the Captain America March from the first Captain America film. Both are by Alan Silvestri (whose best known work is probably Back to the Future), who hasn’t done any subsequent Marvel films. He is returning for Avengers: Infinity War, so there may be hope.
