First of all, do not try to downlaod too many files at once....
If you nrty to download files with many (up to hundreds) of hosts, you will wait till forever after since those files are most likely faked files hosted by those who dislike P2P filesharing.
Try to serach file using "All Types" and try to search for the artist's name or the album. For movies, check the files with Bitzi before starting to download them:
