[3] Fat Mike has further elaborated that the intended second disc of the album did not receive positive feedback and thus it was scrapped.

The video for "Doors and Fours" consists mostly of archive footage of the early 1980s L.A. hardcore scene that NOFX originated from.

A second video released shortly after consists solely of footage of more bands covering the song.

's David McLaughlin scored the release 4/5, stating: "If your mind was made up about NOFX years ago, Single Album is unlikely to change it, but even if this isn't essential for everyone, it is for the band's troubled leader".

[2] Carys Hurcom of Wall of Sound gave the album an 8/10, writing: "Anyone who refuses to listen to NOFX beyond the late 1990's, will be disappointed—some fans will take a while to adapt to the musical variety while others will appreciate the diversity.
