The Westworld season two trailer may have left us with more questions than answers, but fortunately, we can answer one of your most nagging questions right now: the song in the trailer is slow cover of Kanye West's "Runaway." This same tune has been used in trailers for 2013's The Hangover Part III and 2015's The Night Before. The movie and TV industry loves to put Kanye's music in trailers, and it works here. Just take a look at these lyrics:
"Yeah I always find somethin' wrong
You been puttin' up wit' my sh*t just way too long
I'm so gifted at findin' what I don't like the most
So I think it's time for us to have a toast
Let's have a toast for the douche bags
Let's have a toast for the assholes
Let's have a toast for the scumbags
Every one of them that I know
Let's have a toast for the jerk offs
That'll never take work off
Baby, I got a plan
Run away fast as you can"
It's a stretch, but the lyrics do kind of illustrate the dynamic between Dolores and Maeve and their puppeteers. They've been putting up with this sh*t for way too long, and now they're going to run away from this fabricated life. Then again, perhaps the music department at HBO just liked the iconic piano bars at the top of the song.
In any case, here's the full video of "Runaway," off Kanye's 2010 album, My Beautiful Dark Twisted Fantasy.
