Favorite Songs

I've been trying to figure out what my favorite songs are, considering maybe, top 20. Only the top 3 are in any particular order, by that I mean they are my top 3 favorite songs, probably tied amongst themselves.

1-3) O Holy Night - Placide Cappeau (and later translated from French to the currently sung version by John Sullivan Dwight) I love this for the following lines:
Truly He taught us To love one another;
His law is love And His gospel is peace.
Chains shall He break For the slave is our brother;
And in His name All oppression shall cease.

Change Gonna Come-Sam Cooke (give me chills every time I hear it.)

Redemption Song - Bob Marley (very close second is the duet version by Johnny Cash and Joe Strummer)

To me all three are songs about hope, and that's what the writers had when they wrote, there have been many changes since they were written, but we have yet to arrive, sometimes if you listen to the news, you could believe we've gone backwards (war, slavery, suffering, bombing), but then they are stories of the strength of the human spirit and of the love and selflessness that also exists (Haiti.) There is so much work to do, but we are the ones for the task.
