Spring post 1: music as literature

I think music can be considered literature if it has lyrics. Literature is defined as all written works or books and I think lyrics can be considered a piece of literature work. A novel is much different than luther in music because it tells a much longer and complex story. A poem is a short written work that rhymes. Some rap may be considered literature me me if it has genuine lyrical content unlike most of the rap you hear on the radio today. I'm not sure if I would consider an opera or symphony literature because there are no lyrics or words only music.
