Heyas,
For me and I'm sure for many others Ayu's concert performances make me love songs that I didn't like almost at all before. Seeing her passion with singing it live is amazing, and I feel it everytime I listen to the song. If the choreography is catchy, I also see and feel it when I listen to the song.
My songs that I only liked after seeing the concert perfs were:
1 LOVE
YOU (A MUSEUM perf = love)
appears
How 'bout yours?
