There's 4:

Pearl Jam - Just Breath https://www.youtube.com/watch?v=_7ioE4wRil8

Deeply personal song about fears I have

X-ambassadors - follow the sound of my voice https://www.youtube.com/watch?v=BgNrEwWroBo

1st time hearing this song was at one of their concerts. I was ugly crying with about half the venue

Nothing More - fade in/fade out https://www.youtube.com/watch?v=wBC3Tl0dg4M

This hit hard when I lost my grandad

Blue October - 18th Floor Balcony https://www.youtube.com/watch?v=6gePujX0ycI

This was my wife's and I private dance at our wedding. The only people in the venue were my wife and I, and the photographer. It was the last song before we left, and it left all 3 of us in tears.
