actually well I don't listen to Janne Da Arc so I don't know if Janne Da Arc & ABC's music are the same
your boyfriend shouldn't get worried because after all , both bands's songs are sung by yasu . If both artistes disband at the same time , now that's going to be a big problem
that will be the time when I don't know yasu decides to retire from the music industry :x
