I’m not as much of a diehard fan of Metallica as I am of some of the symphonic metal bands I’ve featured so far, but there are a few songs of theirs I’m quite partial to, and “Nothing Else Matters” is one of them.
Catchy without being poppy, it manages to be thought-provoking, dramatic, and uplifting at the same time, and I always find it inspiring. Probably unsurprisingly by now, my favourite part is the guitar solo near the end, a fitting climax of an intensity you wouldn’t predict from the song’s laid-back opening.
The song has an official music video, but I didn’t find it particularly engaging, so I chose instead a video where the author has set the song to a slideshow of images; I find these tend to complement music nicely. [Update: video was taken down, so I swapped it for the official one after all.]
Featured Lyrics:
Never cared for what they say
Never cared for games they play
Never cared for what they do
Never cared for what they know
And I know

Enjoy!

This is my favourite song of theirs too! (…and possibly the only song I’ll ever listen from them haha)
