Which do you prefer and why?
I chose alan because I felt hers brought forth more emotion than ayu's did for me. Her unique voice and style of singing also make the song. There is a certain urgency I feel in alan's that I don't in Ayumi's. It gave me a bit of nostalgia listening to it. Ayumi's BALLAD doesn't really strike me as a ballad, but its still a good song. Though both PVs are filled with longing, I felt a sense of loneliness and a deeper level of sadness in alan's. I did like the visuals in Ayu's PV though, shes so pretty! alan's lyrics sound more sincere and heartwrenching as well.
This is the PV to alan's BALLAD ～名もなき恋のうた～
