This brief set doesn't exactly contain all reggae classics, in spite of the title claim.
Peter Tosh's "Get Up, Stand Up" is here, as is
Bob Marley's "One Love" (in the 1965 ska-inflected version and not the more familiar version from a decade later), and a case could be made that
the Wailing Souls' pop-infused "All Over the World" is a minor classic, but the balance of the disc falls to the commercial dancehall side of things, making this package a mixed bag that seems to lack any kind of internal theme.
