I see many comments saying Disturbed “Sound of Silence” is better so I carefully listened to both. I just don’t hear it as better - it’s ok.
'Better' or 'worse' are very subjective terms. I don't think either one is 'better,' but I found the Disturbed version to be very powerful. I really liked the raspy sound of David Draiman's voice in the song, with the controlled and understated force he used. I liked how the song slowly builds to a crescendo, then back to the quiet almost whisper at the end.
David has a great voice, and I hate to use the word 'wasted,' but let's just say that on most of Disturbed's songs it is lost under the motoring guitars.
