The slow and measured composition of the pop + trance genres begin with an almost inaudible music, and then go on with a beautiful male voice. It is full of violins with very long sound, as well as percussion and drum instruments that are played, most likely, on synthesizers. It leaves some sadness and incompleteness of some of business, which you wanted to do, but didn’t had time to. Under such a melody you definitely don’t want to finish what once have been started – something more active that this song is required.
