The Breaking Bad finale closed with another bittersweet pop song similar to last summer's melancholic montage, which played to Tommy James and the Shondells' "Crystal Blue Persuasion." This time it was Badfinger's "Baby Blue", with lyrics beginning with "Guess I got what I deserved…," and finishing with "The special love I had for you, my Baby Blue…" Badfinger was picked up and produced by George Harrison and Apple Records, and their leader, the late Pete Hamm, would write a number of iconic hits in the harmonic style of The Beatles. A staple of 70s classic rock, the song now has new life as Walter White's signature ode to his chemical mistress, his "Blue Sky" brand of crystal meth. –Eric Gould
