1. I personally like most IU songs, but my favorite is when she sings acoustic songs! Songs with minimal music, just guitar or piano, and IU voice.. oh my god.. and the song don't need to be a sad song. The perfect one is Fields of Gold. I love that song so much!! 2. Next one I like song like Good Day. with minimal dance but really utilize IU's vocal range, the beat is also fun and any IU song accompanied with violin is daebakkkkk <3 3. Then, cute song and sad song ties in last position. I really like watching IU love performance of Boo or Marshmallow because she is sooo cute! but when she sings Because I'ma Woman she can put her emotion also and I really like that!!! What about you?
