hear the chains throughout the song? they are gone by the end... hence the name "Sweet Escape." Definitely a reference to Jesus setting us free from sin and death!
I have two parakeets and the first time they heard this song both of them started moving to the music and slowly falling asleep. This is the only song they do this to. I have tested this several times and i always end up with the same results. its amazing, i love this song so much. So graceful, gentle and moving.
