Snap! collects all of the Jam's singles, from "In the City" to "Beat Surrender," including several B-sides ("'A' Bomb in Wardour Street," "Dreams of Children") and a handful of rarities, like a demo of "That's Entertainment" and the rock version of "Smithers-Jones." For its compact disc release, several songs were trimmed, but Snap! remains a brilliant summation of why the Jam were one of the most important and beloved British bands of their era. The latter-day collection Greatest Hits covers much the same ground as Snap!, but the earlier compilation remains preferable because of sequencing and its inclusion of essential items like "'A' Bomb in Wardour Street" and "Dreams of Children."
