Greatest Hits covers nearly the same ground as Snap!, with all the tracks but "Just Who Is the Five O'Clock Hero" included on the previous compilation. Granted, "That's Entertainment" is presented in the album version and "Funeral Pyre" in its original mix, but the album isn't quite as strong as Snap! Nevertheless, it has all of the Jam's hit singles, making it a thoroughly entertaining record, as well as an effective introduction to the group.
