I'm I know this might be cheating, but I just GOTTA vote for this b-side track to the album called "Free Will". This is my absolute favorite instrumental in music history! Ever! A true masterpiece. It encpompasses everything that defines a mixture of dance/pop/rock. Marr's guitar solo towards the end...simply marvelous! Free Will>>>>everything else!
But if you say "Hey Isamu! That's cheating! You MUST stick the "Electronic" album no exceptions!", then I'll have to pick Idiot Country. The absolute catchiest and infectious tune ever to come out that era. The chorus is just too damn catchy...
"It's an open act of defiance, and it's indirectly at you. We could force some kind of alliance, we could do what we wanted to do. And the young would live forever, and the sun would shine through the blue. If we got our hands on this nation, we could do what we wanted to do..."
