  Shows the page with information about given Music
  
  We should only use GET HTTP verb for safe operations. For
  instance, showing a Music has no side effects, so GET is fine.
  
  We can use templates for Paths, so VRaptor will automatically extract
  variables of the matched URI, and set the fields on parameters.
  
  In this case, GET /musics/15 will execute the method below, and
  there will be a parameter music.id=15 on request, causing music.getId()
  equal to 15.
