Why is everyone so enamored with the song "Hallelujah?"

Why is everyone so enamored with the song "Hallelujah?" Google it. Yes, it has a hauntingly beautiful melody, but it's about sex and carnality, not YHWH. It always makes me cringe when a beautiful word like "Halleluyah" (which means "YHWH be praised") is associated with anything or anybody else. To me, it's blasphemy utter that word for anything outside worship of YHWH.

The totality of His being, and especially His glory are reflected in His name (Psalm 8:1). Psalm 111:9 tells us His name is “holy and awesome,” and the "Lord’s prayer" begins by addressing ADONAI with the phrase “hallowed be your name” (Matthew 6:9).

The third of the Ten Commandments forbids taking or using ELOHIM's name in an irreverent manner because that would indicate a lack of respect for God Himself. A person who misuses His name will not be held “guiltless” (Exodus 20:7).

This song, "Hallelujah", in my opinion, is completely blasphemous BECAUSE of its MISUSE of YHWH's Holy Name - the very Name He gave to Moshe:

Exodus 3:13 Moshe said to God, "Look, when I appear before the people of Isra'el and say to them, 'The God of your ancestors has sent me to you'; and they ask me, 'What is his name?' what am I to tell them?" 14 God said to Moshe, "Ehyeh Asher Ehyeh [I am/will be what I am/will be]," and added, "Here is what to say to the people of Isra'el: 'Ehyeh [I Am or I Will Be] has sent me to you.' "

15 God said further to Moshe, "Say this to the people of Isra'el: 'Yud-Heh-Vav-Heh ( י ה ו ה ) [Adonai], the God of your fathers, the God of Avraham, the God of Yitz'chak and the God of Ya`akov, has sent me to you.' This is my name forever; this is how I am to be remembered generation after generation. (ISR)
