Finally one that is easy! Church songs...
The Lord's Prayer, On Eagle's Wings or Ave Maria, when done RIGHT, will, and on several occasions has, bring me to tears. I remember at my cousin Tammie's wedding tearing up when The Lord's Prayer was sung - my mom thought something was wrong. The woman singing sounded like an angel - I know it sounds corny, but man, it was so beautiful tears just flowed. I had my friends sing at our wedding and had them sing Ave Maria at the church just so I'd be able to really hear it. They did a magnificent job and I cried.
Defying Gravity got me too when we saw Wicked. It was powerful - lyrics & emotion smashed together with a great performer. Awesome. I was so captivated by that one song I came home and YouTube Idina Menzel's version and listened to it over and over again.
I think there would be more if I took the time to really listen to some songs.
