Right. An anthem which is closely linked with German nationalism/Nazism. Are you dense, uninformed, or purposely misrepresenting the truth?

In case it's one of the first two

The anthem was played at occasions of great national significance such as the opening of the 1936 Summer Olympics in Berlin when Hitler and his entourage, along with Olympic officials, walked into the stadium amid a chorus of three thousand Germans singing "Deutschland, Deutschland über alles". In this way, the first verse of the anthem became closely identified with the Nazi regime.[8]

and

fter the Second World War ended in 1945, singing "Das Lied der Deutschen" was banned along with symbols of Nazi Germany by the Allies.

and

After its founding in 1949, West Germany did not have a national anthem for official events for some years despite the growing need for proper diplomatic procedures. In lieu of an official national anthem, popular German songs such as the Trizonesien-Song, a carnival song mocking the occupying Allied powers, were used at some sporting events. Different musical compositions were discussed or used, such as the fourth movement of Ludwig van Beethoven's Ninth Symphony, which is a musical setting of Friedrich von Schiller's poem "An die Freude" ("Ode To Joy").

and

On 29 April 1952, Chancellor Konrad Adenauer asked President Theodor Heuss in a letter to accept "Das Lied der Deutschen" as the national anthem, with only the third stanza being sung on official occasions.

(I.E. the stanza which doesn't include the phrase "Deutschland uber alles")

So yeah. Saying that there was a sudden burst of singing of a song associated with Nazi Germany IS making an implication.
