Interstellar had themes of our current understanding of Quantum Mechanics "entagled particles" in regards to quantifying the emotion "love" across interstellar distances, String Theory's ideas of multiple dimensions which includes the metric of time, and others sciences. Of course, these are written into the narrative and not explicitly stated.

As for music, I'm a huge fan of Blis N' Eso (hip-hop) - especially their song "Addicted". Here are some of its lyrics:
"...Since a foetus, explored life's subtle secrets
From my fingertips to my unique double helix
I can see history, I can see the past lessons
It's your right, never be afraid to ask questions
How can every religion claim to be the only one
How can they preach love yet fight each other holding guns
I think the golden sun may be able to shed some light
I'd rather push peace and knowledge to defend our rights..."

"...We're all equal yet they push synthetic separation
But in this matrix I won't be failin' to make it
This is my cosmos baby, space sailin' with Sagan..."

How about....Who, who, who let the God's out?
