The musician and DFA Records founder told NME that the music produced by such shows is no worse than other mainstream records.
Murphy said: "I'm not really angry or against them [reality TV contests], it just feels like the same s**t as most other pop music. I don't know what the big harm is.
"In one way it's grotesquely honest, which makes me sad were so numb that we're okay with it - with Simon [Cowell] being a piece of s**t and, 'This is how the business is'. That makes me sad that people accept it."
Murphy, who recently said that the upcoming third LCD Soundsystem LP would be the group's last, added that he believes the album format is "over".
