Actually, their two best songs, in my opinion, are:
Metamorphose (my favorite):
YouTube - Lareine-Metamorphose
&
Fiancalles-a French word for engagement I think (second favorite):
YouTube - lareine - Fiancailles
Most people I know agree with me, though, those songs were apparently some of their biggest hits XD Also, take away cross-dressing and the extravagent theatricality and Visual Kei is just regular J-Rock so I think if people run into a Visual Kei band and are surprised by the cross-dressing, it's because they've never heard of this type of music 8/ Lareine, in particular, were almost like a new-age Malice Mizer. In fact, Emiru, one of the members of the band dressed in Lolita and didn't speak-much like Mana.
Kamijo is one of my idols, actually, he's such a masterpiece and his voice is beautiful : )
