ใช้เกณฑ์ 50 ปี ในทุกกรณี
ขอเสริมเล็กน้อยว่า ถ้างานนั้นยังไม่เคยเผยแพร่
ให้นับ 50 ปี จากผู้สร้างคนสุดท้าย(กรณีร่วมสร้างหลายคน) เสียชีวิต
การนับ 50 ปีเช่นนี้ ทำให้เพลงพระราชนิพนธ์ และงานเกือบทั้งหมดของสุนทราภรณ์ ปลอดลิขสิทธิ์ในประเทสไทย
นับถึงปีนี้ 50 ปีที่แล้วคือ 2513 หรือ 1970 กฤหมายไทยถือว่าเป็น สิทธิสาธารณะทั้งนั้นครับ
