I especially like the part of the song where the music just goes, seemingly lead by itself, to a predetermined place. Branford Marsalis' solo in the middle of A Nightingale Sang in Berkeley Square by Harry Connick Jr is my all time favorite. It touches me at my very core. I have also recently love listening to John Mayer, especially live performances, where he just breaks into unbelievable solos. I don't know much about music, but I know that man can play a guitar. I'm listening to Gravity a lot lately, but it's hard for me to nail down my favorite.
If I figure this out right, I'd like to share both those songs with you. What songs touches you emotionally? I would love to hear about it.
