Public Playlist Doesn't Make Sense

[East930th]

Public Playlist "Rock & Roses" (under K-pop) have songs from
"강력하면서도 섬세한 감정을 담고 있는 얼터네이티브 록 음악을 즐겨보세요!"
This is supposedly K-pop/Alternative playlist according to descripition.

However, there are songs from Radiohead, Cage The Elephant, Maneskin, One OK Rock, Childish Gambio, Coldplay.....

Unless this playlist is generated to combine user's history (which it shouldn't since user would be browsing a particular genre) this doesn't make sense.
