Lyric Snippets 2

As per the previous post on this subject the following snippets of lyrics are from the last five songs played on my iPod this morning.

Can you identify the songs?

I think that this lot will prove to be a bit of a test.

1. You look so self possessed, I won't disturb your rest, It's lovely when you're sleeping, but wide awake is best
2. I gotta great idea, I'm gonna wait right here, while everything is adding up
3. Are we too far gone, Are we so irresponsible, have we lost our balls, or do we just not care
4. When me and a bunch of cowboys, rode into Jesse James, well the bullets were a flying, just like a shower of rain
5. And you find out life isn't like that, its so hard to understand, why the world is your oyster, but your future's a clam
