When I'm playing music on my stereo from my PC through USB, turning off the lights on my bathroom on the other side of the wall will momentarily kill my USB driver and as a result Spotify stops working.
Electromagnetic interference is no joke.

Fire is no joke and given the EMI in your place I suggest you take it seriously. I'm not suggesting that fire hazards are exacerbated by EMI but that the sort of environment that has one may be more prone to the other.
For the sake of what ... USD100(?) in time plus some materials you could fix and head off some potentially seriously life shortening problems. If nothing else, you'd keep Spotify working. If it dies say five times a day and costs you a few mins, then that is say 20 mins per day. Cost your personal time at say $20 per hour. Now tell me you can't afford to get it fixed.
... or you could whine about it on HN 8)
Please get some advice: blow a few quid (bucks, whatever) on a sparky. If you have a friend who knows what they are on about then bribe them to come over and cast an eye over things.
Just to re-iterate the point: it is not normal for your bathroom light to cause a USB (bus) to crash in another room.
In my home, a previous owner cut a cable too short and connected the line to ground via a paper clip. Could have killed us.

Not sure if it's the crap speaker bar; power and audio coming from the same chassis using two different cables or the motherboard. Could be a ground loop? Now That I think of it, I'll try to power the USB from a lab supply or beefy USB charger.
Mains noise/spike/brownout coming through onto 12V/5V/3.3V lines.
Relevant to the article too!
Is this true for every component you plug in?
I imagine this is your stereo power supply.
I oddly would love to hear more.
Anyway, my guess is that there's some line noise that isn't enough to mess up the PC, and the PC is passing it along to some component in the speaker that doesn't like it.
