if you want to spend $ I guess ( since it's not out yet ) the MOFI 45rpm LP set would be the way to go , for less a Japanese pressing sounds great and I like the new Box set of the Archives vol 1 .
I have at least 3 copies of her first 4 albums being her folk years and I would say her albums of emotions , after those I would say that she sings more about experiences , IMO .
