In a contemporary review in 1971, music critic
Dave Marsh wrote that although the album does indeed contain "thirteen classic songs," it fails to deliver on any purpose other than compiling the most radio-friendly hits in one place. Marsh added that "no magnum opuses" were included in the collection. "No 'The End', no 'When the Music's Over', no 'Soft Parade'... [it] would have been decidedly uncommercial to have them included here... Of course 'Five to One' isn't here; funny thing, outside of 'Unknown Soldier' none of the Doors' more controversial subject matter is included." Bruce Eder, in his retrospective review for
Allmusic, likewise observed that
13 focuses strictly on the pop rock side of The Doors, and argued that the approach of marketing this side of the Doors separately from their more serious, adventurous, and coarse side was part of what made the band a success with such a range of listeners. Noting that
13 had continuously sold well for nearly two decades, whereas Doors compilations and live albums which freely mixed the band's two sides were much less popular, he saw
13 and the Doors' self-titled debut album as the two main gateways to their work, serving to draw interested listeners in and ultimately lead them to explore the Doors' deeper album cuts. ==Track listing==
