What´s your favorite music of the "The O.C" ´s soundtrack?

i love the first , second and fourth mixes the most; i also love speeding cars (playing during the graduation), hallelujah, and imogen heap's cover of hallelujah (during marissa's death).

I'm listening to the mix CDs right now:D I love Mix1. It's the intro to it all(: (all as in the show). 4th makes me sad
