Why is that saddening? I'm glad to see that American hip hop is as popular as it is in those countries. Makes me even happier when it's an African American hip hop artist.
It's also sad because the three most common word of the song in question ( Dababy - Rockstar ) are: "Yeah" (21 occurences), "Woo" (15 occurences) and "nigga" (13 occurences). The next one in line are "cop", "pull" and "glock" (6 each). This is probably not the culture the US hopes to export.
"My daughter a G, she saw me kill a nigga in front of her before the age of two"
Which to me don't really sound so happy. So if that is really what moves most of the world today, yeah I am a bit sad.
Makes the lyric you quote seem fairly innocent, really.
It's the cultural equivalent of a species making it into a new biome and wiping every species with the same niche.
Americans find it flattering and even positive (because how couldn't be positive it the rest of the world becomes more like yourself ?) but it's really quite dramatic.
I do wonder if expanding the site to show, say, the top 5 instead of just the absolute top song would be a better indicator; as it stands, it feels like Rammstein was right: "We're all living in Amerika".
