}}[[Image:Echoplex.jpg|thumb|Artwork accompanying the MP3 file]]'''"Echoplex"''' is a song by [[Nine Inch Nails]] released online via Facebook on May 2, 2008. It is the fifth track on the album [[The Slip]].
The artwork may symbolize someone being surrounded by sound, as if it were echoing around them. It may also symbolize walls around the person, which makes sense due to the lyrics making a reference to sound bouncing off of walls.
