You're talking about Franz Liszt.
think the best music come from people themselves. everyone has a song at the bottom of thier heart which brings him /her memories, or once touched his/her heart in some cases.and about singers, if they really into music and wana be famous and bring people great music, i think they will try to be as skilled as they can.music is like dedication and each has its own reasons to come out to the world and known by people.
