Q: Bought this for my 5 year old Justice Leaguer. My son is not a rough player but we went through 4 (YES, FOUR) of them before we finally got one where the elevator didn't break in the 1st 2 weeks. Mattel needs to get their act together and design toys that have durability. VERY disappointing!

A: Negative
****
Q: 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!

A: Negative
****
Q: I don't care about all the hype, I dig this record a lot. I play it, then I play it again. it's almost always in my head. I wish I had four more of her records. the performance is very loose and the production is really tight. rollicking, rowdy, catchy as hell. she's got a great spark.

A:
Positive
