This is impossible to answer, I mean how can I pick one song from the greatest band of a l l time?
That said, picked the song "One" but depending on the day it could be about 7 or 8 others. You would almost have to break it down album by album to have clear winners and even then competition would be fierce.
Is it bright where you are? Have the people changed?
This song is almost flawless it's has everything, Good drum Track, awesome riff's throughout, great mid part duel harmony from James and Kirk, one of Kirk's best solos all wrapped around easily Cliff Burton's greatest work on a bass guitar and even 2 bass solos thrown in.
Honorable mentions for - Dyers Eve, One, The Outlaw Torn and Ride the Lightning
Edit- Technically Blitzkrig and Am I Evil are not Metallica Songs they just covered them.
