I agree that it's impossible to compile a definitive list. Some very beautiful songs which I've been listening to a lot lately (trying not to repeat artists too much):
Damage - Sylvian/Fripp
She Gets Out The Scrapbook - Furniture
The Song of Solomon - Kate Bush
This House - Alison Moyet
Chariots - Transglobal Underground
But I'll probably have a whole new list next week
