This song is Annie's ost, and I thought it was strange that several ost had the same rhythm, but I just thought about something. When we read the lyrics of "Call of silence", we notice that they are incredibly consistent with Ymir's situation, the singer comforts her and offers her to be reborn and to really live now. For "Call your name" I have the impression that the singer might be Annie's father, who explains their situation and why he had to sacrifice his daughter. He did not have the power to improve his situation but his daughter, she had this power. The singer also talks about a lover and a brother who has disappeared. We have never seen Annie's mother and we have no information about her past.
And if ost were another way for Isayama to tell his story. Especially since the last words:
"And I got no power. I'm standing alone. No way. Calling out your name"
And if these words were in fact a prediction, a prediction on the end of Annie and the manga. The Eldians standing alone, and Annie's father calling her, knowing that she will not come back ...
What do you think ? In any case it is clear to me that Isayama uses ost to tell his story in another way. Even the titles of these two songs are similar and the rhythms and almost the same
