There seems to be some trackerproblems on Queenzone, so you should use utorrent or ?(bitcomet?) www.utorrent.com
available in multiple languages.
As mentioned install this small program and open the file on the topic you want to download and utorrent opens automatically.
Never download more than 2-3 torrents at the same time and keep on seeding after you finished downloading, so that others can finish as well. ;-)
If you have a fast connection you might be able to download more torrents at one time? I don't know.
Look out, take care, there's a lot of music out there...
