I have an issue where my account appears to be shared with a stranger from the other side of the world. Each time I log into my spotify it says X is playing on his device etc etc. We play device ping pong for a while before one of us eventually gives up. The same works in reverse where I will be happily playing my music and it suddenly cuts out. We also appear to be sharing playlists where one will create / delete the others music.
I have reset the password etc ect but nothing seems to make a difference. It appears more like the database thinks the account is the same.
I am not alone yet radio silence from spotify:
