One of my favorite things about Seoul is that you cant walk a block without coming across a coffee shop, whether a chain store or little hole in the wall. Convenience stores are stocked with shelves of little coffee cans, and theres even a shop in Hongdae that makes portrait latte art. Korea is basically heaven for coffee lovers.
This is true with music too. The Korean indie scene as well as the K-pop scene is full of songs that could fill a proper coffee-shop playlist for days, and there are even plenty of songs about coffee too. Been through a break-up and the smell of coffee makes you nostalgic? Theres a song for that. Feeling something as addictive as caffeine? Theres a song about that. Is your daily, cheap coffee as bitter as how your current life makes you feel? Theres a song for that, too.
