Luis you can perform it all you like but you cannot broadcast it so no TV YouTube or anything like that. Actually all of Vigil's work is like that it pays to read the copyright information on any product. Spelmann's work is exactly the same and so are many others. Think of it this way whenever anyone plays a song on the radio in a shopping centre or anything of that nature they have to pay who ever has the publishing rights to use it. Why do you think all the songs they use on idol are owned by Sony? By owning the publishing rights to the song they don't have to pay to use it and if the original singer has a problem they should not have sold them in the first place.
