Ok this is creepy:
Over the past few years, Spotify has been ramping up its data analytic capabilities in a bid to help marketers target consumers with adverts tailored to the mood they’re in. They deduce this from the sort of music you’re listening to, coupled with where and when you’re listening to it, along with third-party data that might be available.
And they’re not alone:
Spotify is far from the only platform helping brands target people according to their emotions; real-time mood-based marketing is a growing trend and one we all ought to be cognizant of. In 2016, eBay launched a mood marketing tool, for example. And last year, Facebook told advertisers that it could identify when teenagers felt “insecure” and “worthless” or needed “a confidence boost”.
