Whats more of a straight up fraud of 2 outta three is "why isnt that enough?"
Left in the dark is a betrayal song. a song you play when you feel betrayed or lonely. Its actually a very suicidal track, like Steve said.
I thought the only "clones" on BFG were DIMP (paradise wannabe) and Stark Raving Love (which is in the realm of Took the Words)
i see no similarities between BFG and Bat.
