3 Doors Down downloadable track
 

I recently went to Best Buy and bought a copy of 3 Doors Down's current album, Seventeen Days. There was a sticker on the plastic wrapping that said that I could get a free downloaded song. I opened the case up and there was a little card inside that said in order to download the song, I have to have Napster and a Napster account. I know that Napster's downloadable, but I really don't want it. I'm an iTunes gal. I'd like to know exactly what the song is (the card didn't say) and if it's worth downloading (if it's some acoustic version of one of the songs on the album, I'm not interested).

So, does anyone know what the song is? Is it any good?
