The intriguing, haunting music has been one of the lasting conversations around HBO's Westworld. Okay, besides the theories about alternate timelines, advanced existential theories, and even “Hey, what planet is this thing even on?”. After those, though, it's definitely all the cool piano covers of contemporary songs.

This Week's 'Westworld' Changes the Game Who's actually in control here, anyway?

In the first five episodes, we've already had weird, somber player-piano renditions of Radiohead's “No Surprises” and Nine Inch Nails' “Something I Can Never Have,” and a fun, caper-y version of the Rolling Stones' “Paint It Black.” Now, Hitfix reports that you can buy some of the covers that appear on the show on iTunes, meaning you're one step closer to your very own robot saloon where everything is totally fine and nothing could possi-blie go wrong.

The songs are little more than cool Easter eggs to spot in a complicated, heavy show; a bit of fun amidst all the weird cryptic underground conversations and head smashing. But it was probably a welcome bit of levity for composer Ramin Djawadi, who you also know from Game of Thrones, who told Vulture, "It's a Western theme park, and yet it has robots in it, so why not have modern songs? And that's a metaphor in itself, wrapped up in the overall theme of the show."

Of course, one can't write about Westworld without deep-diving into some weird-ass theories. Presumably this means Radiohead exist(ed) within the universe of the show? How far into the future is this? If you can use a band's songs in the park, why wouldn't you FILL this park with cool old-timey versions of celebs? Maybe they're saving a robo-Jagger cameo at the piano stool for a ratings boost in Season Four.
