I have been learning Russian for a while and listening to Russian Music. My first question is, can there be two stressed vowels in a word? Does it matter? How do you say Narod (country)? There are two stressed vowels a and o.

Secondly, in normal Russian accent, I have observed they don't care about the yery. I am careful about pronouncing it like Y (mix the symbols both Latin and Cyrillic sound LOL). But I heard:

Oy da ni vechyer da ni vechyer
Oy mne malym ma lospalos

They pronounce the yery similar to English say

Isn't music a bad option for learning the pronunciation? We have to change the stress of vowels to match the tune.

What do you think?
