Understanding lyrical content has always been of secondary importance to me, either due to it being in another language or having content I couldn't parse.
From when I was very young, I remember my grandparents and others singing or reciting nursery rhymes to me in Polish, High German, or Yid. Reunions & holiday gatherings always had lots of singing, and my extended family often sang in Czech.
Russian wasn't spoken in any of my family households, but I often heard pre-Soviet or pre-Nazi era music being being played at family functions (most having left prior to the farm collectivisation & purges in Russia, or as the Nazis were coming into power).
Conversely, I've had friends that absolutely hated music which contained lyrics in other languages (or even English dialects); as kids, they were never exposed to anything other than American pop, rock, r&b, or country music. My wife was one of those people, but she came around fast once.
For as much as I dislike YouTube as an entity for their business & social practices, it's still our digital age's visual & audio Library of Alexandria. Without it, I'd never be able to expose my infant daughter to the variety of music that I was afforded.
And it seems to be working with my little girl. She absolutely loves certain things like rural E. European & Japanese acapellas; Siberian, Mongolian, and Tibetan polyphonic singing; Polish polka and Imperial German drinking or martial music (often one & the same), Native American powwows/chants, old Norse... hell, even French jazz. No videos, audio only.
