Huh? It has an awesome ending. Maybe there's a problem with your CD. You really should buy it rather than downloading it off Kazaa.
I actually downloaded a torrent of Images and Words back in 2006 (when I was first getting into the band), and in the description it said "the first song is corrupt", so when I listened to it, sure enough the song cut off at the end. I faded it out, and that was what I listened to for a while. Then I discovered DT.net, and found out it was supposed to be that way.
Of course, had I listened closer, I would have heard it didn't actually "cut off", but the torrent description said so, and I was a DT noob.
