The philosophy of life, according to hair metal

1. You should be up all night and sleep all day.
2. Rock and roll is not really noise pollution.
3. I don't know where I'm going. But I sure know where I've been.
4. Rock and roll all night, and party every day.
5. With love we'll find a way just give it time.
6. You don't need nothing but a good time.
7. It's OK to have love in an elevator.
8. You really can be too young to fall in love.
9. We are the youth gone wild (well, I was when this song came out, I'm not so wild now, though I did buy a six pack of Sam Adams Cherry Wheat).
10. We're not going to take it anymore.
11. Everything starts to spin loaded on gin.
12. Life is just a fantasy, but can you live the fantasy life? (I love it when bands get deep)
13. You take your road, I'll take mine. The paths have both been beaten.
14. It's not what you got, it's what you give.
15. Rock. Rock. Until you drop.
16. You don't know what you got until it's gone.
17. Wherever I may roam, where I lay my head is home.
18. Stop wasting time always searching for your wasted years.

Can you name the bands putting forth these nuggets of wisdom?
