The song is on the new Flyleaf CD, Memento. The band were horrified—as all decent people are—at the figures stating that 2 million children are victims. And that number is just the kids.
The band’s tour is entitled , the Unite and Fight Tour because they want people to unite and peacefully oppose this gruesome practice.
You can do more than just download a free song as well. You can donate by text. I have been assured 100 % of the money goes to World Vision to fight human trafficking You can text UNITE to 20222 and $10 is added to your cell phone bill. The money then goes to World Vision to rescue victims of sex slavery.
I always recommend looking into a charity before donating--there have been some issues with World Vision in Liberia. But it doesn't seem there was deliberate malfeasance on their part. Regardless it is a good idea to do some research on your own on any charity before ponying up money. Look to see if they meet your standards and conform to your beliefs. If not, there are lots of other organizations you can donate to to help exploited kids.
Nonetheless the band's heart is certainly in the right place.
