I've realized that the music doesn't always loop. It doesn't even always play all of the songs you have on there, it chooses certain ones every time you open the Client and plays those repeatedly, but some times after it runs through them it doesn't play through them again. So you get stuck, playing to nothing until you get a chance to close and open it up again. I've got more than 80 songs on my list and I only hear a maximum of 15 a random amount of times before the music completely stops playing.
