IMO Their best over all album is Defenders of The Faith but the best song imo is Electric Eye and especially with the intro or instrumental before it The Hellion is the bands best song. It is one of their fastest, heaviest, and even "thrashiest" yet has a good smooth groove for a better lack of a description along with very tight musicianship and a great production quality. It has time changes yet are smooth along with Halfords better vocal attempts as he changes his range very nicely with the time changes. A very well rounded song that is very very hard to beat imho.
