Have a go.
Mine would be a bit hard to decide, but 'Angie', 'Let it be', Moby's 'We are all made of stars' and 'Slipping away' would be on the list. Oh, and 'Breakfast at Tiffany's' by Deep Blue Something. And U2's 'One'. And 'Rufus Wainwright's 'Hallelujah'. And Mylène Farmer's "Dessine-moi un mouton".
Crap, there's no end to this....
