"The Masses Against the Classes" is a song by British rock band Manic Street Preachers, released as a limited-edition single in January 2000.

[2] "The Masses Against the Classes" is considered a return to the alternative rock style of music produced by the band in the early to mid-1990s, while the lyrics reply to criticism of the This Is My Truth Tell Me Yours album, which had featured a softer, more pop-oriented sound.

[4][unreliable source] Martin Power proclaimed "The Masses Against the Classes" a "raucous, guitar-driven slice of pop-punk" that recalled Nirvana's 1991 song "On a Plain".

The concert at the Millennium combined with "The Masses Against the Classes" reaching number one as well as the top 20 in three other countries, and the fact that This Is My Truth Tell Me Yours was a commercial and critical success, is frequently pointed as the peak in the Manic Street Preachers' career.

[4] "The Masses Against the Classes" was released both as a CD single and numbered 10-inch vinyl; each version also featured the songs "Close My Eyes" and a cover of Chuck Berry's "Rock and Roll Music".
