I was trying to be a super spy at the time. Can't remember if Spotify was even available, but if it were I wouldn't have used it, cuz I was trying to not have any crossover identification between phones (like a paid for login). That limited what I could do so much I ended up not using it.
Lesson I learned was I'm no super spy, and should t try to be. Reading a bit from a post nostr:npub1klkk3vrzme455yh9rl2jshq7rc8dpegj3ndf82c3ks2sk40dxt7qulx3vt out out recently (can't find it rn) about graphene reminded me that it's not only about being a super spy, which I concede I can't do, but breaking some tracking of oneself. And that's good enough for me.
