The 2000 re-release which was used for promotion of Thankful
"Shackles (Praise You)" is the debut single by gospel singer-songwriter duo Mary Mary, released in 1999. It is considered the group's signature song. Stan North of GospelFlava.com deemed it one of the pioneer songs of urban gospel music. The song was originally recorded and released in December 1999 upon Mary Mary's signing with Columbia Records and was re-released one month later as a promotional single for their upcoming debut album, Thankful. They both feature the same track listing but different album covers, the second using a picture of the duo. Mary Mary later shot a music video for the song.
"Shackles (Praise You)" became a crossover hit, being popular with gospel, R&B, and pop audiences. It was a Top 10 R&B and Top 40 pop hit, and peaked at #28 on the Billboard Hot 100 chart. It became the first gospel song in five years to crack the R&B top ten and gained wide exposure on the MTV video cable channel. In addition, "Shackles" was one of the few gospel songs to receive significant airplay on many CCM stations and appeared on many compilation CDs (including WOW Hits).
It was also a worldwide hit and reached number 5 in the United Kingdom and number 17 in Ireland.
