Despite appearing to have a .zip extension, the "attachments" are really hyperlinks to the actual zip files hosted on Google Docs. If you click on one of the links, it should take you to the Google Docs site. I was prompted to sign in with my Google account, and was then able to download and unzip the FLACs with no problems.
Listening to them as I type this. Great stuff!
yes, music is great (i can play tracks with winamp) but I didn't get linked to google docs and I do have a google acct which I don't use very much. Hopefully, the cd arrives today
