六人行第一季第七集里面罗斯被猫抓的时候菲比一群唱的是啥歌？下一集里的lyme是啥意思？

菲比一群唱的是：
Top of the world
歌手：Carpenters 专辑：carpenters monument

Such a feelin's comin' over me
There is wonder in most everthing I see
Not a cloud in the sky got the sun in my eyes
and I won't be surprised if it's a dream
Everything I want the world to be
Is now coming true especially for me
and the reason is clear
It's because you are here
You're the nearest thing to heaven that I've seen

I'm on the top of the world lookin' down on creation
and the only explanation I can find
Is the love that I've found
Every since you've been around your love
Put me at the top of the world

Something in the wind has learned my name
And it's tellin' me that things are not the same
In the leaves on the trees and the touch of the breeze
There's a pleasin' sense of happiness for me
There is only one wish on my
