Surely the intro to "dont look back..." is one of the best intros in ages! it builds and builds, from soft and rhythmic to urgent and frantic, then a crashing slide and a spine-tingling yelp (yaaah-aaaye!), and it explodes into life, bursting with vibrancy in every note...its just brilliant! The intro alone stands up the hairs on the back of my neck every time, but its a gem of a pop song, really heartfelt too, i love the line about the song at the death disco..."it started fast, but it ends so slow, and all the time it reminded me of you". Like i said, a gem!
