Lyric discussion by llamapro999 

Cover art for Echoplex lyrics by Nine Inch Nails

The repetition of the line: "just like they said" makes me feel like the narrator felt no control over his life, and the line: "my voice just echoes off these walls" to me means that sometimes, no matter what you do, your voice will not be heard. The end of the song seems to be a 'giving up' in a way. It seems that since his voice will not be heard, he won't even bother.
