"Sad But True" is a heavy metal song recorded by Metallica for their fifth studio album, Metallica. The song was released as the album''s fifth single in mid-1992. This song is about a drug addiction and how it can, and will, take over your life. Though the band had utilised the ''D standard'' tuning for the recording and subsequent performances of covers such as Crash Course in Brain Surgery and The Small Hours, this was the first instance of the band utilising such a low guitar tuning for an original piece (The Thing That Should Not Be is an exception as it was recorded and has always been performed in the ''D standard'' tuning, not Drop D). Bassist Jason Newsted tuned his 5-string bass down to ''A standard'' for this song, which is essentially the equivalent of D standard, i.e. one whole step down.
