My iTunes spaffed up this week when it updated. After uploading an old library, I noticed Annie Mac's Minimix in the list of podcasts to which I no longer subscribe. After sorting it out, I decided to subscribe again and lo and behold the first one to download was Zinc's classic history of D'n'B mix from 2005.
You can try this hotlink for it on iTunes (I think) or right-click below and "Download Document".
