The Most Beautiful Song of The RnR era?

Thanks for the ideas, everyone.

To clarify:
R'n'R era really means music made by rock musicians. Since the idea is to debunk his notion that rock musicians haven't made any beautiful music, I thought a well selected compilation might broaden my father in law's view of "r'n'r" songwriters while allowing me to get in some contemporary music listening time during the family vacation. Though some responses went a different way (my original post was worded more generally), I'll look forward to exploring some of those suggestions for my own benefit.

Beeswing did refer to the Richard Thompson song. If my FIL is ok with RT's voice, I'm betting he'll like the song.

Thanks again, everyone.

The recent post was certainly...comprehensive!
I actually finished 2 cds using many of the recommendations you all so kindly posted. Some people tended to favor beautiful singing, so I did one cd focused this way, while another focused on beautiful songs - often sung by less than beautiful voices. The initial response from my father in law to both cds could probably be best characterized as "grudingly positive".

Thanks again,

Marty.

Kris,

I agree with your general sentiment which is why "Hello, It's Me" was the second song I listed in the original post. The guy is just a machine - cranking out amazing songs year after year. Some of his lyrics push it a bit, but the melodies and - especially - harmonies usually stop me in my tracks.
