Lately, I seem to purchase new music, only to find out that another retailer other than Amazon has bonus tracks that are not on the one I purchased. Target, Walmart, and others often do this, and I feel cheated because if I want the new tracks I have to buy a whole new CD again. That's why I'm hesitant to "pre-order" anything these days when it comes to music.
There's an extra track (A live version of Introduction) on the Japanese release, but folks in Canada and Europe who have already received their Cds don't have that track. As Ruth said, the best place to order is from the band's website. They've already provided a mp3 version of the cd for those of us who have preordered.
