Maybe not my very favourite...I don't know if I have one of them, but here's one I like a lot:

Pop music often tells you everything is OK, while rock music tells you that it's not OK, but you can change it. There's a defiance in rock music that gives you a reason to get out of bed in the morning. Most pop music doesn't make you want to get out of bed, I'm sorry to say. It puts you to sleep. -Bono
