help!

its the ep where heidi is supposed to go away for her mum's birthday
but instead turns up to area and surprises spencer
where he is with those playboy girls
she ends up crying to lc while lc is on the phone to spencer trying to sort it out

anyway the episode ends with a song, sung by a girl
that goes something like "i thought the world was round"
i cant decipher much else of the song
but i really wanna find it

thanks!
