“Butterfly” is the acoustic finisher to Weezer’s cult classic “Pinkerton”.
It’s a slow and solemn number which will make anyone become teary-eyed, especially after listening to the previous nine songs.
“Pinkerton” was written during a period of turmoil for the band’s lead singer Rivers Cuomo, and you will never hear anything that could detail the feelings and emotions that he felt as you do in this album.
You should really listen to the album as a whole before listening to the song. At least that may give you something to lean on. When you’re sad and feeling lonely, you might not want to listen to “Butterfly”. It might make you feel worse.
