Someone is apparently using my account? i keep seeing that someone using a Nexus 5 is using my account to listen to weird Forign Music. Should i change my password? i did change my password, and haven't seen them since, BUT, How did they get it in the first place? is it because my account is linked to my Facebook? is someone on my Facebook? is there a flaw in Spotify somehow?
What should i do, and any idea how it happened?
