Awesome hack. You send a text message from your mobile phone to your POP email account. Your text message should containg the keywords of a song title (and possibly an artist name) that you want to hear. DittyBot finds that email (he checks Mail every 45 seconds) and copies the song name into a text file. The song name is then copied into iTunes and a playlist is created from your search. Next, DittyBot loads Skype (the internet telephony app) and begins calling your mobile phone. Your mobile phone rings and when you pick it up, you should hear your song start playing in all its compressed glory. Link.
