Both are beautiful songs. From my understanding, "Stupid in Love" is basically about a broken relationship between two people. The boy accuses the girl of various things, and the girl always responds with "that's not what I mean," or "nan ani aniya" (I'm not sure how accurate that translation is).
I really like Mad Clown's voice. His lines are sharp and fast-paced.
"Stupid in Love"
I love this performance of "Eyes, Nose, Lips"
"Eyes, Nose, Lips" is a song I fell in love with the first time I listened to it. Taeyang has a really beautiful voice and a lot of talent.
