@MattNewberry Please add this to constructQueryBody function. You can change the following lines
if command == "ALBUM_FETCH"
            body += "<GN_ID>" + gn_id + "</GN_ID>"
    else

to 

if command == "ALBUM_FETCH" || command == "FETCH_SEASON"
            body += "<GN_ID>" + gn_id + "</GN_ID>"
    else
