Tried to find the audio but unfortunately it seems that the audio file for your flight at the time of your go-around was missing the portion where your flight did the go-around. Most likely there was another flight that landed before yours and may not have cleared the runway fast enough or maybe a departing flight couldn't start their takeoff roll quick enough for whatever reason and that's why the go-around. It's interesting that another flight (AAL943) was also told to go-around about ten minutes after your flight but probably not for the same reason.
