Serbia is a close second, in my opinion. It's just a simpler version of The Emperors hymn by Haydn, with lyrics that consist of begging god to save the country. The fact that it replaced the old anthem (Hey, Slavs) irritates me to no end. We used to be a country
Honestly "Bože Pravde" would be like a middle tier anthem like Hungary's, if it weren't for the context of the fall of Yugoslavia. That context alone makes Serbia's anthem bottom tier.
I don't have an exact ranking of bad national anthems, but I've always found Norway's anthem to be profoundly tedious and bottom tier. The only thing Norway's anthem is good for is letting me subvert the opening line by saying "No, we hate this country as it falls down", but as an anthem there's just better choices out there, and there's better anthems in the Nordic countries. Like even Denmark's "King Christian Stood By Lofty Mast", for as much as it pains me to award points to a song praising a monarch, at least that anthem is the only national anthem in the world to include the word "brain" in its lyrics.
Interestingly enough, people mostly don't associate it with the Germans. The majority of people here don't know about the fact. I'd doubt it would get any love if that was the case.
If anything, it's very fitting that we have knock-off German anthem in this era where we don't have any sovereignty.
