Indians win the pennant - and they play that cheesy love song sung by Bill Medley.
I know this thread is about the music, but I still have no idea why that game was played in Cleveland.
Edit: finally looked it up. Apparently until 2008(?) home field advantage in a one-game playoff was determined by coin flip instead of head to head record. Carry on...
"Come a Little Bit Closer" in Guardians of the Galaxy 2. James Gunn always calls that song "the ultimate fight song" and I have no idea why. The song isn't remotely about fighting. It's a fun song, but... weird choice.
