I've noticed a number of visitors trying to access the Pandora "world of Parchment" radio station we created some time ago. Many will have been disappointed because, for some reason, Pandora's activities have been restricted to the USA recently. The issue appears to be something to do with copyright licensing.
This is sad as Pandora offered an interesting collection of music, old and new, along with quite a sophisticated analysis. It introduced me to quite a number of bands and singers and led to the purchase of a number of CDs, It had just included its first Parchment tracks, from the Under the Silent Tree compilation CDs.
The last.fm radio site contains a Parchment page and a "Parchment" radio channel, largely based, so as I can see, on the Folk is a Four Letter Word 2 CD. Last.fm also has a small "Xian folk" group but the station doesn't seem to have the range of Pandora.
