I like that explanation.
Usually for me, I tend to consider song structures quite important. Metal typically has longer riffs than hardcore/metalcore/heavy punk subgenres, or nu-metal, or more mainstream hard rock. Metal usually has more sophisticated song structures than most other rock, often more like the 'movement' based genres than pop and rock with verse-chorus-verse structures.
The boundary between progressive rock and metal I find harder to define besides 'uhh, is it heavy?'.
In my opinion this is correlation rather than a defining feature in that the type of musicians that go into metal tend to want to make more complicated songs. They also typically aren't trying to pump out 3 minute Radio hits
There are a lot of complicated rock songs such as:
The Beatles 'A Day in The Life'
Queen 'Bohemian Rhapsody'
The Who 'Behind Blue Eyes'
Jethro Tull 'Locomotive Breath'
Led Zeppelin 'Stairway to Heaven'
Styx 'Come Sail Away From Me'
Lynyrd Skynyrd 'Free Bird'
Muse 'Knights of Cydonia'
Obviously some of that is progressive rock, but it's the mainstream friendly progressive rock and not say Gentle Giant, and I included a lot of not progressive rock.
Whereas something like Electric Eye (which is still awesome) isn't really all that complicated. BTW looking back at my OP, somehow I left out Judas Priest and it's too late for me to edit it.
