A nasheed (Arabic: نَشِيد, romanized: nashīd, lit. 'chant', plural Arabic: أَنَاشِيد, romanized: anāshīd) is a work of vocal music, partially coincident with hymns, that is either sung a cappella or with instruments, according to a particular style or tradition within Sunni Islam.
In Soviet Union, the rock genre was for a very long time existing underground due to the inability of artists to be properly published.
Only starting with the 1980s could the artists finally publish their songs officially. And even then Soviet government put a lot of measures to prohibit rock music in the country.
This resulted in the appearance of many beloved bands and artists, like
Kino (tl. Cinema),
DDT,
Aria,
Chaif,
Grazhdanskaya Oborona (tl. Civil Defense),
Mashina Vremeni (tl. Time machine),
Sektor Gaza (tl. Gas Sector)
Korol i Shut (tl. King and Jester)
And many others
The history of Russian rock is actually quite fascinating. It was inspired by bard songs and often touched darker subjects as well as being satirical and judgmental of Soviet government.
Due to that, some artists, like Yegor Letov from Grazhdanskaya Oborona and Yuri Shevchuk from DDT, had troubles with KGB (Soviet FBI).
Nowadays, rock artists are still being persecuted for their views. For example, DDT is de facto prohibited from performing in Russia.
I think you seriously over-estimate the level of tolerance of Nazi Germany. The Nazis persecuted Degenerate Music just like they persecuted Degenerate Art.
I'm not saying that Nazi Germany didn't ban music, they absolutely did ban entire genres of music as well as many composers. But they didn't ban music based on its basic qualities like tempo.
