Someone copied my playlist and is raking in the subscriptions!

[7characters]

I hate to throw my toys out of the pram here (really I don't care, and that is in fact what I’m doing in its entirety) but someone has copied my 3600+ subscribed to playlist - same songs, exactly the same order - renamed it, publicised it and made it their own.

Please can we copyright playlists, Spotify? I like having loads of subscribers and I don't want to share them!
