There are tons of Metallica MIDI files out there. The only problem is, many of them sound like shit. So, I picked out the best ones I could find. I don't plan on spending too much time searching for new MIDI files, so if you think that you found a better one than I have, feel free to e-mail it to me. My address is metcomp@mailcity.com. The songs that really impressed me are 'The Call of Ktulu', 'Orion', 'One', and 'Fuel'. However, these things vary on different sound cards, so don't take my word on it. Enjoy.
