The question is: what is the point of God wanting us to praise Him? Does that sound to you like a reasonable “desire,” or a reasonable request…? By contrast, what would we think if Bibi asked that of us…? More precisely, I’m not sure there actually is such a request from God, but there is a midrash that sounds as though God “longs” for it. As it says that from Adam until the splitting of the sea, they did not sing praise, and then “the Holy One, blessed be He, said: for these I had been waiting.”

And if you say that the whole purpose of prayers and praises is only for us and not for Him, so that we strengthen ourselves spiritually and in the service of God in one way or another—for example, that we remember Him, or remember the kindnesses He does for us—then apparently that is not how it sounds from Psalms and from several midrashim and elsewhere. And there are places where this issue is seemingly presented as a central part of creation, if not the purpose of creation, so it is certainly not just a practical means for fulfilling commandments or something of that sort.

I don’t see a basis for the discussion. Do you really understand what the Holy One, blessed be He, wants and why? Are you attributing to Him desires like those of human beings? Maybe it is intended for our sake (gratitude, accepting His kingship)? Or perhaps these praises repair Netzach within Hod?
I don’t know where it implies that the praise is not for us, but as I said, it doesn’t really matter.

An ancient topic; see Berakhot 7a, in the story of Rabbi Yishmael and Rashba, in the aggadic discussions there. And from there, explain it.
