now that you've mentioned it 
but was thinking "love songs".. what kind.. the bocelli type? the
sappy crappy useless boy/girlband types? the tender lovesong
type?
there are some really from the heart types which get to you, like
the silly fella, John Denver's couple of odes to his wife, Annie's
Song and Perhaps Love...
maniac singers showing their tender sides like Iggy Pop's Candy and
the ones i mentioned...
exquisitely crafted ones like Bocelli's "time to say goodbye"
and then, a few, no words are needed.. like Joe Satriani's Always
With You, Always With Me...
