Your income wouldn’t exist without the existance of your parents. This does not mean they own your income. You are arguing based on a contrived and unuseful philosophical basis. Who owns the data is a matter of law not philosophy, and having laws like GDPR looks like a great way to empower consumers, so who cares if the data would not be there without Spotify? It would not be there without the consumer either, in fact Spotify itself would not be there without the consumers... should the consumers then “logically” own Spotify?
