i always pirated music through download addons, knew my playlist perfectly because i spend a lot in headphones during day, and even tho i got tons of indi rock shit back then i was shocked to hear something unknown to me in my playlist. For few moments i legit thought that my phone possesed. Turns out that apple could download anything on your phone just because you connected to wifi without your consent. Even tho i never buy anything in their music shop.
