Music as literature

I would say of course we can consider music as literature because the only real difference of the two is that music tells a story or is trying to put out a message in more of a fun way that people can enjoy. We describe literature as written work on a specific subject like a book on how to become a farmer or anything like that. The only differance I see between all those is the way they are given to the people. One is expressed in a song, one is a book, one is a play but the one thing they all have in common is that there all trying to say something to reader/ observer.
