> One of the task of store employees is to report how many customers they notice using Shazam in the store

Fascinating. Do you remember your source?

Well, shazam could sell that info to the stores

heck, they could even tell by sniffing wifi traffic

I wonder how many people actually end up connecting to the store wifi.

Or you install a DAS in the store and monitor the traffic of phones connected to that.

I think they could just get your MAC address if you have your WiFi turned on, without you actually connecting.

iOS doesn’t allow this any longer.

location + time + song = exact match

Of course, you'd have to trust Shazam to provide accurate data.

On iOS, Shazam is usually used through Siri (it's beyond me why anyone would download the standalone app).

I wonder if the connection is made straight from the iPhone to shazam, or Apple actually proxies this.

It was an article about a UK playlist selection company which had 6 millions yearly revenue doing this. Unfortunately I can't hit the right keywords now to find it again.

What a delightful discovery, this playlist selection vertical.

Going down that rabbit hole, I discovered some gems:
