A brief diversion

Name the song and artist without using Internets.

No prizes, only prestige.

1. I'm so tired. I need sleep. I'm talking to my pillowcase - what's wrong with me?
2. Now that I have found someone I'm feeling more alone than I ever have before.
3. Is there a melody that could lead you to me like a lullabyed child led to sleep?
4. Hearts getting broken lead to people growing cold.
5. You're a big boy now, so let's not talk about growth.
6. Will I shake this off, pretend it's all okay?
7. The road is long; there are mountains in our way.
8. Give me your lips and with one kiss we'll begin.
