Watch This Incredible Microscopic Footage Of A Needle On Vinyl

Okay, I bumped this video ahead to the part where you can actually see the super-zoomed-in footage of the needle in the grooves.  The entire video is long and on the technical side, and sorta makes my brain hurt.

I still have essentially NO IDEA how records work. I don't get how a guitar and bass and drums and keyboards and vocals can be transferred through a microphone onto a piece of vinyl, and how that tiny needle can turn those seemingly random grooves back into music. I mean, I understand the concept (I think) but I still can't fully wrap my mind around it.

Regardless, it's really really cool to see the needle bouncing around those grooves like that.
