Want to get a free song and fight AIDS?

On iTunes, for the next 24 hours, U2's song Invisible will be free to download, and for every download Bank of America will give $1 to RED, an HIV/AIDS charity. I don't care what you think of iTunes or U2, please don't bitch about them in this thread. Just, if you do have iTunes, please take the minute or two to download the song. It's the right thing to do.
