Quora Answer : What is the best song ever made, and why?
I Will Survive by Freddie Perren and Dino Fekaris. And famously sung initially by Gloria Gaynor
Why is it the best song? Because it scores consistently highly in pretty much every dimension you want a popular song to score highly in : great melody, great dramatic arrangement, words that capture a mood and tell a story perfectly, beat that makes you want to dance, creates a party vibe, sing-along-ability etc. etc.
It's not necessarily the best song in any of these specific categories. There are better party tunes. More profound lyrics. Better melodies. More musically sophisticated songs. Songs which are easier for a crowd to sing along with. But I say that no other song is consistently good in all of them as I Will Survive. It's the best "all rounder" song.
And it's unsinkable. However you mangle it in a cover version, as long as you basically hit the tune and words, then it's an enjoyable listen.
Quora Answer : What is the greatest song ever?
The best song ever written is this.
There are many different dimensions of song-writing. Some people care about lyrics. Some about whistleable melody. Some about dancing. Some about feel. Some about musical craft. Some about the emotional honesty and storytelling.
I Will Survive isn't the "best" in any of these dimensions. But it's the song that scores most consistently well across every one of them.
There are songs with better lyrics that are worse to dance to. Songs with better grooves have less beautiful and catchy tunes. Etc.
But nothing does EVERYTHING to such a consistently high standard as I Will Survive.
