Share a lot of your musical tastes to your Twitter friends? TweetTheBeat [iTunes] is the perfect app for tweeting your favorite songs on the go (since Last.FM won’t do it with YOUR own music). And it’s free.
Tweet a track that you’re listening to right now via your iPhone or select one from your library of music. You’ll need to hand over your credentials (no oAuth support), and TweetTheBeat will then create a preview tweet of the music being sent. A link to preview your song using twt.fm along with the song title, artist, and hashtag #tweetthebeat is the standard and unfortunately, you can’t change the message. You can only cancel or confirm the posting from here.
We just wish this app gave us the option of selecting another twitter music services instead of being stuck with just one.
