Quando, Quando, Quando is one of my favourite late night songs.

It really sets the mood for a calm, beautiful night at home. Very Euro with its essence and centric arrangement, mixed with that smooth Latin sound, ugh, perfection. Nelly sounds beautiful, never would have imagined she'd be so compatible with this type of song but WOW. She really blew me away with this the first time I listened to it, and I still love her on it. Gorgeous duet.
