Trust me, you'll need a black magic marker. I'll explain in a minute.
Overall, this isn't Aimee's best collection of songs, but it does feature two must-have songs: "Deathly" and "Save Me". Many of the other selections are a bit of a departure from her style, and they come across as a frolic--swing beats, jazz motifs, bubble-gum pop, etc.--to be taken as a bit of tongue-in-cheek. As several reviewers have pointed out, the themes are depressing. Duh. In the liner notes, it's said that the entire Magnolia film was built around the rather nihilistic Aimee lyric: "Now that I've found you, would you object to never seeing each other again?" Personally, I love it.
About the magic marker...
Before you put in the CD, take a fat magic marker and draw a 1 centimeter line from the inside (hub) of the disc radially outward. This will effectively delete the four last songs so that you never have to endure them. They weren't written by Aimee, and they have no business being on this compilation at all.
