From 1991, Metallica is one of my favorite heavy metal albums. It is a strong album that has some of their best songs. My favorite is "Enter Sandman". Other songs I like are "Sad but True", "The Unforgiven", "Wherever I May Roam", "Don't Tread on Me", "Through the Never", "Nothing Else Matters", and "The Struggle Within". Metallica is an album all heavy metal fans will want to hear.
