[Q]: El primer libro del Dr. Weiss sigue siendo un gran libro para todos aquellos a quienes les inquieta el tema de la reencarnacion, asi no crean en ella.
[A]: Positive

[Q]: I don't actually own this album, but I did buy Apple Venus, and I'll say this: I hope that this album has the charm that that album lacked. I've never been so disappointed with an XTC album. Why would one buy an album of the exact same songs, except in demo form? A shoddy attempt to extract money, it seems. Shame on you, XTC!
[A]: Negative

[Q]: The book was new and in perfect condition. The price was well below that of many competitors. It was sent in a timely manner. I would gladly buy from this company again.
[A]:
Positive
