I can't stop listening to AR Rahman's Fanaa and Bring me to Life by Evanescence. Some of the other songs in their Fallen album are super too. I first heard Bring me to Life when I saw Daredevil, but got the song much later from louiswu. Amy Lee has an amazing voice!!!
Its fun when you think of a song and can download it in under 2 minutes thanks to a fast internet connection :)
