Dolly的《Plastic Tree》的歌詞如下：
Plastic tree, plastic tree
Living in the plastic world
With my plastic dreams
Plastic tree, plastic tree
Living in the plastic world
With my plastic memories
I can't cry, I can't cry
Cry all night long
I can't die, I can't die
Die in this world
Plastic tree, plastic tree
Living in the plastic world
With my plastic memories
Plastic tree, plastic tree
Living in the plastic world
With my plastic dreams and memories
Plastic leaves floating on the sea
It doesn't care if it gets washed away
Stars shimmer in the endless sky
Away from my life and love far away...
《Plastic Tree》是Dolly在日本人氣動漫《XXXholic》的劇場版中的一首插曲，深受聽眾喜愛。該曲節奏舒緩，表達了一種迷離而淡泊的情感，如同在講述一個永恆的故事。歌詞中的“Plastic Tree”指的是塑膠製品做成的樹木，暗喻著人類在現代社會中的虛無感和孤獨感。
