An application called Song Sender has just been released.

When you run the application, it reads your entire library, creating a list of the music on your iPhone. If you tap on a song, the screen will fade out and give you a list of options: Play the song, stop playback, send to email, or send to ringtones.

It is pretty nifty. I didn’t think it would be to useful for me, but I was a little wrong. It works perfectly, and I love it.
