Got a favorite song you’d like to share? That’s awfully nice of you. Fortunately, sharing a tune on Twitter is easy if you use any of the following music sharing sites:
1: Blip.fm (http://blip.fm/). This site lets you set up your own broadcast station. Create an account and then configure it to share with Twitter by typing your Twitter credentials. Locate a song from the Blip.FM archives, click Blip, type some text to appear in your tweet, and then click OK.
2: Song.ly (http://song.ly/). This site is a combination music search service and music sharing service. Type an artist or song title and click Search, and Song.ly looks for matching music on the Web. In the results (see figure 9.8), if you see the song you want to share, click the Tweet icon, sign in to your Twitter account, and then post the tweet.
3: Twiturm (http:/twiturm.com/). You can use this site to share your own music by uploading an MP3 file, or to share Web-based MP3s by specifying a song’s Web address. Log in with your Twitter username and password, and then click Upload. Specify a local file or a Web address, type a message for the tweet, and then click Upload.
4: twt.fm (http://.twt.fm/). This site is by far the most popular music sharing service among Twitter users. Twt.fm associated with IMEEM (http://imeem.com/), so it has access to the millions of songs in the IMEEM database, but twt.fm can also locate music streams on the Web or share your MP3 links. The home page asks for your Twitter username, an artist name, and a track name. Click Preview and, if twt.fm finds
