Inception.

I don't actually understand how people had difficulty understanding Inception.
I just watched it for the second time and woah! I love it!
Stuff to do with subconscious and conscious mind is intriguing to say the least!
I also love the soundtrack.
Its so haunting and yet so equally uplifting.
My favourite would probably be "Dream is collapsing" or "Dream within a dream" because its similar =)

Heres links to good versions of the songs:

• Half remembered dream
• We built our own world
• Dream collapsing
• Radical notion
• Old souls
• 528491
• Mombasa
• One simple idea
• Dream within a dream
• Waiting for a train
• Paradox
• Time

Or if you want to listen to all of them here's a playlist:

• Inception (12) playlist

But its definately a soundtrack to listen to.
DEFINATELY... Mmmmmm!
