I like all their albums for various reasons (save for Load and Reload). [spoiler]Kill 'Em All- Has this youthful, unabashed crazy sound that I find fun and exhilarating, a sound most notable in one of my favorites on the album, Jump in the Fire. Ride the Lightning- Still retains that youthful spark that Kill 'Em All has, but at the same time you can clearly hear where the band has matured. Great song writing too, I especially like the song Escape even though Metallica themselves hate the song. Master of Puppets- What is there to say about MoP? It's a great album. ...And Justice For All- As I said, I like all the albums (save for two) but if I had to choose a favorite, it'd be AJFA. I just love the tone of the guitars on the album, I could faintly hear a song playing and immediately know that it's an AJFA song, that's how recognizable the sound is and I just love that. Another thing I like about the album is the subject matter and the lyrics, two of my favorites on the album being The Frayed Ends of Sanity and Eye of the Beholder. Metallica- I'm just going to say meh. I don't dislike it, but I will say this, Enter Sand Man was a song that kept me from liking Metallica for a long time. It was all I'd hear on the radio, so I thought they were a crappy band (I don't mind the song now though). Load & Reload- Not even going to say much as I've never bothered to listen to either in full. I like Fuel and some other songs from one of the two. St. Anger- This album is what got me into Metallica. I don't feel like going to to detail, but I actually like the album, except of course for Lars' stupid snare (it sounds like he's making popcorn in a trashcan). I will admit though, I don't really care for the singing and the lyrics of the songs any more, but I do still like the music in majority of the songs. Death Magnetic- This album is also what got me into them. I know some fans would probably say "Why? It -blam!-ing sucks." I like it because at the time, all I was hearing was Enter Sand Man, so when I heard All Nightmare long on the radio, I was pretty intrigued as to what else they had to offer, although I'll admit it took me a couple of years to actually listen to their older stuff.[/spoiler]
