I feel guilty about this (I'm a Beatles fan with an 'old school rocker that hates pop
and stuff that's not based on guitar-bass-&-drums' attitude) but...

mango - flor de verano ("summer's flower") aka "bella d'estate" (the italian version)

just a pop oldie from the 80's that I find very sad,how could a song be that sad??,
aaargh,I listen to it and I feel soooo saad! aaaaaayy!!
