Glory and Sadness, Beauty and Pain

X is a song written by Y and famously covered by Z. Time Magazine’s Josh Tyrangiel described it thus:

Y murmured the original like a dirge, but except for a single overwrought breath before the music kicks in, Z treated the 7-min. song like a tiny capsule of humanity, using his voice to careen between glory and sadness, beauty and pain, mostly just by repeating the word X. It’s not only Z’s best song — it’s one of the great songs, and because it covers so much emotional ground and is not (yet) a painfully obvious choice, it has become the go-to track whenever a TV show wants to create instant mood. ‘X can be joyous or bittersweet, depending on what part of it you use,’ says Sony ATV’s Kathy Coleman. ‘It’s one of those rare songs that the more it gets used, the more people want to use it.’
