I have used http://www.deezer.com/ for a while now and it has always been in English. Recently it is showing everything in French. Google Chrome will auto-translate pretty OK but why is Deezer suddenly French?
It turns out the language in settings was set to French. Don't remember ever setting that and not sure why I would but there you go.
Go to 'Cog' (top right) > Settings
Then select your preferred language > Save
