Music playing from other devices

[SlymZ]

This started today morning I want to know if I'm the only one, I don't share my account with anyone, honestly I thought I got hacked, but since today I was listening to music has I always do but somehow looked like somebody else was playing music on my account I I couldn't listen to what I wanted to, I already talked with customer support and the solution they gave me was to change password and log out from other devices also they said there where logging from different locations, I was just wondering if I was the only one.
