I love Russian music and have long found it a great way to improve my Russian language level. Through songs, you can learn vocabulary and phrases that help make you sound authentic. And listening to Russians sing definitely can do wonders for your phonetics.
I recently wrote about three of my favorite Red Army marching songs at Explore Russian: explorerussian.com/learn-russian-songs-red-army-marches/. In my blog post I explored the backstory and lyrics of these three songs below: Farewell of Slavianka, We Spin the Earth, and Sacred War.
By the way, if you’re looking for more Russian songs to practice your language, I definitely recommend exploring Angelos’s music resources at Explore Russian. My favorite is his grammar analysis of Вечная молодость / Eternal Youth!
You can find a list of Russian Film Hub’s collaborations with other online Russian resources here.
