You think Im sarcastic... but I actually fall asleep listening to Behemoths new album... specifically Daimonos.
Just skip to 0:30 unless you want to hear a chant.
For some softer stuff I can think of the quieter sections of some songs from the Black Clouds & Silver Linings album by Dream Theater. Not wither though.. I just dont like that song, its like its not Dream Theater, almost like a completely different band. In the Presence of Enemies pt2 isnt so bad either.
Opeth DEFINITELY has some soothing songs, especially on their Damnation album.
