It's our fifth birthday, and true to form we're celebrating Pet Shop Boys style. We haven't got many left in the bank now so we hope you enjoy our penultimate PSB album episode, and it's a super sized one at that! This one is celebrating the joy of 'Fundamental'. If that isn't enough this is also our 250th album episode, what a double bubble milestone. Let us know your thoughts and memories and top tracks @trackbytrackuk
