The quality is amazing!
Ne-Yo is one of my favourite artists, and Sungha's playing "So Sick" from him! Ironically, I've never listened to the original, so this sounds like a kdrama soundtrack to me. What do you think?
I know everyone's probably sick of this song, but it's worth a listen from Sungha. He takes out the whininess from the original and creates something soothing.
