It Miek (sometimes appearing as "It Mek" or "A It Mek") was a 1969 hit song by the Jamaican musicians, Desmond Dekker & The Aces. After being re-released in June 1969, the single reached number 7 in the UK Singles Chart. The track was written by Dekker (under his real name of Desmond Dacres) and his record producer, Leslie Kong, and was recorded in Jamaica with the brass accompaniment added in the UK. It spent eleven weeks in the UK chart, and by September 1970 had sold over a million copies worldwide. A gold record was presented by Ember Records, the distributors of Dekker's recordings.
The song's title is Jamaican patois meaning "that's why" or "that's the reason."
