"Redemption Song" by Bob Marley is a reggae song that Sawyer sings in "Exodus, Part 2". It was likely chosen to emphasize recurring theme of redemption on the show. The first lines, although never sung aloud by Sawyer, match with Walt being captured later in the same episode. "Exodus" was also the name of a popular album by the same group, although "Redemption Song" itself is not one of its tracks.
Old pirates, yes, they rob I
Sold I to the merchant ships
Minutes after they took I
From the bottomless pit
But my hand was made strong
By the hand of the Almighty
We forward in this generation
Triumphantly
Won't you help to sing
These songs of freedom?
'Cause all I ever have
Redemption songs
Redemption songs
Emancipate yourselves from mental slavery
None but ourselves can free our minds
Have no fear for atomic energy
cause none of them can stop the time
How long shall they kill our prophets
While we stand aside and look? Ooh!
Some say it's just a part of it
We've got to fulfill the Book
Wont you help to sing
These songs of freedom? -
'Cause all I ever have

Emancipate yourselves from mental slavery
None but ourselves can free our mind
Wo! have no fear for atomic energy
'Cause none of them-a can-a stop-a the time
How long shall they kill our prophets
While we stand aside and look?
Yes, some say its just a part of it
We've got to fulfill de Book
Wont you help to sing
These songs of freedom? -
'Cause all I ever have:
Redemption songs
