Remark: for the title in Japanese, there's not the ":" before the number 4, on the CD or on the side/obi. I don't have this CD, but I have another CD of this collection "Memorial Songs" ("Getter Robo", the number 3) so it should be certainly identical for all the CDs of this collection. Plus on the CD, the number is circled.
