Need some help with songs..

I am not that sentimental and am having trouble picking a father daughter dance song.
Any ideas?

Also need a cake cutting song and a groom/mother song.
Why is this so difficult?

well for father/daughter we are doing beauty and the beast because my dad and i use to dance to that in my living room when i was little.

cake cutting we are using U2 the sweetest thing

mom/son dance is the man you've become

i danced w/ my FIL and we danced to '100 Years' by Five for Fighting.

Our cake song was 'Love You Madly' by Cake. I thought we were pretty clever .
