It's called Suicide & Redemption, its 9:58 from Death Magnetic. The Outlaw Torn is actually 9:49, as a correction for a previous answer

Actually Mercyful fate is 11:12 long, as a correction for a previous answer

Answer 2

No technically it is called junior dad at 19:29 but this is not part of Metallica a discography it is Lou reeed but they were featured in this song but the longest is mercyful fate at 11:10 and yes this is their song because mercyful fate didn’t put it in a medley

suicide and redemption
