Wow Jackhammer has differing tastes then others related to music. Write this moment in history down...Hateful is a great song in my top 5 from the album.
I find it destroys the integrity of an album to place emphasis on certain songs. I'm not saying there's anything wrong with having favorites, but I've always been against the purposeful division of an album into singles and filler tracks. Anyways, London Calling is a great record. Too difficult for me to pick out what I like when all of it is so solid.
My favorites are "Guns of Brixton," because of its ominous guitar melodies; "Brand New Cadillac," since I love punkabilly; and "Death or Glory," for its fast, catchy vocals.
