I too am fixated on the Boarding music payed on AA International flights. I searched and it is produced by Music Bakery of Dallas. The title is "Beyond Words" and can be downloaded from their website. Enjoy!

I listened to it for 3 plus hour over and over flying from DFW to PDX the other day!!!! Call me crazy but it is very soothing.....no wonder they use it to calm everyone trying to board a crowded 777.
