As a musician and musicology student, I am very familar with both the "classical" world of music, and the popular world of music, and I have to say that perhaps string quartet versions of R.E.M. might be interesting, but you need a creative and enterprising quartet (such as Kronos Quartet, etc.) to do this. This CD is greatly disappointing because the transcriptions are simplistic and lacking imagination. String quartet recordings can be very exciting, but not here!

I love my Zen Xtra 40GB - well at least I loved my Xtra. The player is great, except for one major detail - the shoddy quality of the headphone jack. IT WILL FAIL! If you get lucky it will still be under warranty. If you aren't expect to pay at least $40 for the clowns at Creative to fix it. If you think I am just flaming them, check out their forums.

I do own this toy, and is a huge fan of the film, so this toy for me is very nice. It may not be very durable, or does much, or may not look like the reall thing very much, but that is why you can still pretend with it. The toy itself lights up and makes noises. Also, when you press a button on its back, its wings and legs spread out, so like the Duel Disk Launcher, it could hurt a real little kid, but not kids who know what it does. I still have fun with the toy, plus it doubles as a model for those out there who like the model Yu-Gi-Oh! products. Although not one of the greatest toys to role of the line, but still nice to play with.
