Well, shazam could sell that info to the stores

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.

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.
