When I first saw this thread I thought it was some sort of joke. Now that I see you are serious…
“A national anthem is a generally patriotic musical composition that evokes and eulogizes the history, traditions and struggles of its people, recognized either by a nation’s government as the official national song, or by convention through use by the people.” (Wikipedia)
As such, I vote for “Lulay Torascha”. Alt: “Shir Hama’alos Beshuv Hashem es Shivas Tziyon”. 🙂
They evoke our struggle and hope.
