I don't think she's done one yet. Even the ones with lyrics that could be interpreted romantically are shown not to be very romantic in her PVs. I think many of her outwardly romantic love lyrics actually speak more of loving oneself. Rainbow is a good example, and perhaps ANGEL'S SONG is too. On one episode of Ayuready? with Kyoko Fukada or Maki Goto she states her belief that one should take care of oneself first after the guest asserts this sentiment. I think so much of her music has to do with the self, and that every song has a little bit of this. In other songs, rather than be overtly in-lovey, she seems to prefer to take on a the role of a muse instead, speaking for everyone in love. In PVs such as appears, YOU, For My Dear..., and TO BE, she seems to be an observer commenting on what she sees.
Y'know, one of those songs that sounds really heavy with emotion. Like "Drive" by The Cars or somethin. Or like some of Andrea Bocelli's pieces.
Maybe Dearest comes closest? There always seems to be an uplifting quality in her music. Perhaps her heaviest lyrics occur in Memorial Address, especially in how the song ends; nevertheless, I think the instrumentation when the song moves into rock is uplifting. Even though the lyrics portray a vulerable speaker, the way she sings them gives the speaker strength. If the song had stuck with classical instruments the whole time, I believe we would have one profoundly sad song. She doesn't seem like a person who would do a really heavy song, but I wonder what such a song would sound like coming from her.
You guys know what I mean in general? I don't connect Ayu and romantic love songs. If you were to pick an Ayu song to play while you're at home cuddling with your loved one, would any of them fit? If you think any of her songs are really ooooh romantic, please post and say why you think so! Would you like to hear more of it from her? If you agree with me, would you like her to try doing a romantic love song?
