Anyone notice how similar the outro theme of YFNSM sounds similar to the iron man 3 theme

I was recently rewatching iron man 3 and notice how similar it’s main theme is to the YFNSM end credits theme. So listened to the end credits theme and to me they both sound similar. I would post a video of the two things but the sub Reddit won’t let so just search up a video of the two themes and see if you can hear an resemblance to iron man 3’s main them
