13 tracks is going to be awesome. I remember I loved Threshold to death when it came out, but by the time I got to track 10 or so, I was totally burnt out. It was cool that there was still a ton more tracks to listen to later, but the problem was, I never really felt like I actually wanted to go back and sit through the next 15 songs. In the end I more or less made myself do it, and I ended up not enjoying them nearly as much as the first set. It's kind of like Plastic Beach.
So this is going to be awesome.
