Collected contains material from the band's albums Three Dollar Bill, Yall$, Significant Other, Chocolate Starfish and the Hot Dog Flavored Water, Results May Vary and The Unquestionable Truth (Part 1).

[1] The music of Collected has predominantly been described as nu metal[2] and is noted for "kinetic, frenzied energy".

[4] His guitar playing on this album also makes use of octave shapes, and choppy, eighth-note rhythms, sometimes accompanied by muting his strings with his left hand, creating a percussive sound.

[7] Borland's guitar playing also has unevenly accented syncopated sixteenth notes to create a disorienting effect, and hypnotic, droning licks.

Allmusic's James Christopher Monger gave the album 2.5 out of 5, writing "Fans of the raucous rap/nu/alternative metal outfit would be better off with 2005's Greatest Hitz compilation".
