FWIW, I stopped using Azureus b/c it was an absolute resource hog. But I know the latest versions of BitTornado and ABC support d/ling individual tracks. In ABC, right-click and select Torrent Details. Then switch to the File Info tab. Then select ALL the files, right-click, and select d/l never. Then go back and select only the file(s) you want to d/l, right-click, and select d/l normally. Same sorta thing in BitTornado, too. Great feature.
