Additionally the single also peaked within the Top 10 in Belgium, Finland, France, Ireland, the Netherlands, Spain, Sweden and Switzerland. On the Eurochart Hot 100, "Iron Lion Zion" peaked at number 8. Outside Europe, it reached number 2 in New Zealand, number 71 in Australia and number 11 on the US BillboardModern Rock Tracks chart. A remixed version was released as a single and later included in 1995 on Natural Mystic: The Legend Lives On.
Larry Flick from Billboard wrote, "Rockers' reggae with pop swing and dance sizzle, this propulsive, previously unreleased jewel from the new "Songs of Freedom" boxed set features a wonderfully exultant vocal from Marley, plus the terrific horn of Courtney Pine. A smash in the U.K., it deserves to explode here. And don't miss the 12-inch Kiang club mix."Music & Media noted that it was "one of those previously unreleased tracks in the 4-CD Marley box. Of course it's a little bit reworked in the studios with additional musicians such as the jazz saxophonist Courtney Pine and female vocal trio I Trees, featuring Marley's widow Rita. Bound to be a classic like the posthumously released Buffalo Soldier in 1983." Alan Jones from Music Week called it a "Marley masterpiece", adding it as "a hugely commercial, lightly dubbed and joyous reminder of his talent". Eric Snider from the Tampa Bay Times described it as a "infectious" track.
