Bluetooth turntables.
A friends 14 year old daughter has one. Turntable is in the living room, speaker in her bedroom.
When she’s listened to one side of an album, she texts her mum and asks her to turn it over. 
Ah
Clever girl. She must have observed how cats train their staff to do what they want done.
which goes with the apocryphal
‘what did your last slave die of?’
‘she/he didn’t, she/he is in the kitchen’
This made me laugh 
At first I thought this was one of those tests to see whether you misread what was written…
I have a friend exactly like this.
When I was in retail customers would come in and ask for a dem. I’d of course ask them, “what sort of music do you listen to?”
You’d expect the answer to be a little generic like “Jazz” or “Rock and classical" but it feels like 8/10 blokes would honestly say, “I mostly listen to Pink Floyd. Dark Side of The Moon. That sort of thing.”
I’m very responsible. I’ve only the one.
One each on record, CD, Bluray and SACD…
It’s less funny if you really hate Pink Floyd and people keep coming in to spend 15K on a system (circa 1995 prices) but claim to only listen to DSOTM and nothing else.
You start wondering what alternate reality you’ve been sucked into.
I suppose it could be worse - at least they (claim to) listen to the whole album. They could have just said ‘I mostly listen to the rototoms in the intro to Time’.
I prefer the alarm clocks.
