I just bought this CD "Single" ("Baka Survivor" by Ulfuls) and I really love it!
I have always enjoyed the song "Baka Survivor" a great deal, (it is an awesome song) and I am very glad that I finally decided to go ahead and purchase it.
As a bonus the CD arrived VERY quickly and was in perfect condition.
EDIT: Plus the CD also has a second track on it (the CD actually contains two songs), and the second track is rather nicely done as well.
That being said, "Baka Survivor" is still my favorite song on the CD.
