Be sure to speak VERY CLEARLY. Sometimes, it doesn't recognize what you say perfectly, and so you may have to try again.
What it does
You call it, asks for the song artist, and the song name. The service will look for the song and sing it back to you. It will also attempt to get the mp3 and text it to you.
What's next for SM(p3)S
Better production environment, where I'm not testing in prod anymore. Also, major bug fixes xD
