I went for that, AND SO CAN YOU! It gives you a choice of 4 songs with no option to stop. To hear a different song, you have to hang up and call again, though I didn't try just letting the song end. It's a very simple system and gave me a system error on my first try. "To hear One On One... press 1", heh. I C Wut U Did Thar.
