2.Metallica - Ride The Lightning

3.Slayer - Reign In Blood

5.Machine Head - Burn My Eyes

Some albums are really good. Many of these are good all the way around. And, in many cases, there is a single song that stands out, sometimes it's the last song on the album. This is a list of those songs.

For a more in depth look at this, I've codified each into a given category:
Type 1 - 'The long song at the end.' Often the title track. These have a tendency to be most well written and dynamic pieces on the album.

1.!T.O.O.H.! - Order And Punishment (Řád A Trest)

2.Abigail Williams - Becoming

3.Agalloch - The Mantle

4.Amon Amarth - Versus The World

5.Anekdoten - Vemod
