What Ever Happened to the Summer Blockbuster Movie Theme Song?

There’s no post-credit scene in Avengers: Endgame. There’s no great power ballad or uplifting arena rock singalong; no ode to Thanos; no “Ballad of Tony Stark;” no Dion, Mellencamp, Tyler, Swift, or Loggins to see us out. And the same can be said of other recent summer blockbusters like Wonder Woman, or of any of those ludicrous Transformers films, or even of the most recent Pixar films.
