Oh god there are so many:
Cancer-My Chemical Romance, Dark Paradise-Lana Del Rey, Moments-One Direction, Small Bump-Ed Sheeran, Skin and Bones-David J. Roch, You Really Got a Hold On Me-She & Him, Unintended-Muse and Follow Me-Muse
The beginning of Follow Me is the sound of his sons sonogram and he wrote it for his son and he just looks so emotional and sincere when he plays it live. Here are some of the lyrics " you can follow me, I will always keep you safe, follow me, you can trust in me, I will always protect you my love, feel my love." like if that doesn't just make you want to ugly cry then I don't even know.
