What's your favourite subtle needle drop in the MCU?

Most of the time when there's a song in a movie it's designed to stand out. Led Zepplin's Immigrant Song in Thor: Ragnarok, ELO's Mr Blue Sky in GotG Vol 2. or No Doubt's Just a Girl in Captain Marvel for example. There are countless bangers in the MCU. But sometimes they sneak in a clever little background song that just adds to the movie without being in your face about it.

My personal favourite is The Underdog by Spoon. It's at the start of Spider-Man Homecoming when Peter is riding the subway on his way to school. It's only instrumental without any of the lyrics so it easily goes by unnoticed. Except it's one of my favourite songs and I got very excited in the cinema when it played. The whole song is great and is a nice little foreshadow of how Spidey will be treated, both by Tony and Adrian/Vulture. The chorus says it all, "You got no time for the messenger, Got no regard for the thing that you don't understand, You got no fear of the underdog, That's why you will not survive"

So what other hidden gems are lurking in the soundtrack of the MCU?
