From Oceansize alone, I think their discography contains some of the most damned beautiful stuff I ever heard, but these two have to be the most beautiful onse:

From Radiohead, I would say they have a large amount of beautiful ambient songs, especially many in In Rainbows, but this has to be the obvious winner:

From Muse, OoS and Absolution are two extremely diverse albums with lots of beautiful moments, but Micro Cuts has to take the cake, for Matt's amazing vocals:

From Opeth, sure they are a death metal band with a lot of beautiful ambient/acoustic interludes, but Damnation was a damn beautiful Prog album:
