I first thought it was neat. Personal library, like how Streama is a personal Netflix. Then I saw it's another service owned and controlled by someone else.
Don't get me wrong, I don't know you, and im not going to assume bad behavior. But this is a treasure trove of data, and you cannot guarantee that if acquired, another party wouldn't exploit it. If it were local or on a machine I controlled, then I could guarantee data security and privacy.
Enough of my life is on the "cloud" controlled by interests that are different, and sometimes oppositional to mine.
Thank you, but no.
