I'd have to agree with some of Psychick's choices. Also apologies if these have been mentioned but I'm clicking every youtube link to find out the name of a song.
I'd have put -
Guns n' Roses - November Rain
Boston - More Than A Feeling
Nine Inch Nails - Right Where It Belongs
and last but not least, my favourite :
Antony and the Johnsons - Hope There's Someone (this is a link to the song. There is no video, just audio)
