Swg.fm is a new web service which allows you to share songs on Twitter. Unlike other Twitter service, swg.fm does not require your Twitter login password, it only requires your username. You can enter your username, Artist name and song title and click send. Swg.fm will create a Tweet with all the details of the song and artist.
The service generates a tweet and opens up Twitter page with this tweet, which you can publish after logging into Twitter. The tweet includes a URL and also the name of the song your are sharing. The shared URL will open up a swg.fm page with the song loaded in YouTube.
The service basically searches YouTube for videos of the songs added to the tweet and displays them in the shared URL page.
Swg.fm is an interesting web service to share music on Twitter without you having to search the YouTube URL. Since YouTube has almost all categories of videos including different languages, it will be easy to share music.
