I just got her "new" CD this week, featuring "Wreck of the Day ('06)", and I can say that it was worth more than the $2.79 I had to pay in shipping for it. Though there's not very much on it to recommend anyone (other than a fan) to get it if they've already got the original version, if you have neither version, I would certainly recommend this version because it features the original version in its entirety, plus a new take on "Wreck of the Day", and three demo songs that make me love her voice and writing style even more than before.
"Wreck of the Day ('06)" emphasizes its triple-meter feel more than the original record, and features entirely different instrumentation. The tempo is just a touch faster, though not too much, and is in a slightly higher key. Her vocal has a lot more color to it, and overall the music sounds a touch brighter than the original.
The three demo songs at the end are very well-recorded, and "Drink Me" particularly sticks out to me not just because of the intriguing poetic references in the lyrics, but the way she bends them around such a mesmerizing melody. "More Than Melody" also has a melody that in places catches me in a similar way.
