Like Paul said, you need to use a downloading program to download the files (limewire or bitorrent or similar), the torrent is like a link that the torrent downloader needs to start the download.
if the files that you have downloaded are only a few kb's then that is just the torrent or link file, and you need the downloading program.
if it is mp3's you are downloading then they should be playable in any music player. a whole album would normally be between 50 and 300mb's depending on file type and quality.
hope this helps.
