What does music do for you?

This is something that is a really big debate between me and other people in my family/immediate circle. So, my parents say that music is important, yeah, but it's just a combination of sounds that make us happy or sad. It's 'just music'. And then my friends and I sit there, so stunned, because if it wasn't for music we probably wouldn't even be here. We've had a lot of issues (who the hell hasn't) and our favorite bands have gotten us through that. The lyrics of every song give us hope and make us happy when the world goes to shit. Because Pierce the Veil made us feel like we had a home, Sleeping With Sirens gave us hope, etc. What is music to you? What bands make you believe life is worth it and everything will be okay?
