Mininova.org, a famous Torrent indexer website has recently launched a new feature to their website, actually to their new website ‘bitlet’ :). BitLet is similar to a torrent downloader application but its web-based, and its best feature currently is that you can listen to music torrents rather then having to download the torrent on your computer.
Above this text is a screenshot of how the new Streaming music looks like on mininova.org at this moment. Not all torrents hold this feature, the embedded green layer saying “Stream this music”, but no worries you can still listen to the songs you want even if it doesn’t look like that.
How does it work? well this is quite simple. “The torrent must contain ogg vorbis or mp3 files.” - Bitlet.org. In other words, as long as your torrent file (.torrent) contains a set or just an .mp3 or ogg vorbis file then it will auto detect it for you and list down the songs for you. Here is how my list of songs look lik, all I have to do is click on one and it will play it for me.
So, check it out on your own, experiment with it. The founders of mininova said that they are working on enabling users to Video Stream in torrents..so music and video streaming. 
Good effort Mininova.
I guess the image is a bit larger then I expected. Oh well :).
