The last song was "Sarcasm" by Get Scared. No one guessed it correctly.

Song:

I apologize, I'm not a mind reader

I need attention so I try to be a crowd pleaser

It was easy 'till it got a little deeper now I don't know how to deal with it so Imma disappear

I'm a ghost

Now you see me, now you don't

(I feel like this is a fairly well-known so g so hopefully someone can guess it-)
