Music can change the world because it can change people.
Pop music often tells you everything is OK, while rock music tells you that it's not OK, but you can change it.
If you pour your life into songs, you want them to be heard. It's a desire to communicate. A deep desire to communicate inspires songwriting.
Music fills in for words a lot of the time when people don't know what to say, and I think music can be more eloquent than words.
