The Kill by 30 Seconds to Mars
This was the first song I heard from the band that I've been in love with for years. It's no longer my favorite (Hurricane holds that place now), but it's still an amazing, energetic and in-your-face song that I've listened to over a hundred times according to Last.FM stats. It still surprises me when I look at Jared Leto that his voice can be so strong when he turns from speaking to singing.
What if I wanted to break
Besides the pausing, I love this video - it takes an epic song and puts it in a classic movie, Kubrick's version of 'The Shining'
