Atheist songs
What would the world be like if there was nothing to oppress people? No money, no power, no religion?
It’s almost impossible to imagine, though very appealing.
Lingua della canzone: Inglese
A translation of John Lennon's "Imagine".
Lingua della canzone: Lombardo
The paradox of an infinitely powerful and benevolent God, and all the evil in the world, is one that’s apparent to anybody with any common sense.
Yet, no religion could come up with a reasonable solution, except that of "you need faith".
A song to definitely and irrefutabily dismiss the absurd theory of Darwinian evolution.
Lingua della canzone: Inglese
A song for stalwart supporters of sacred unions between people loving each other. That is, as long as they differ in their 23rd chromosome.
Lingua della canzone: Inglese
Christmas is a time for celebration for many religions. It makes you wonder which one is right in their claims.
Lingua della canzone: Inglese
This is actually a whole album (the linked song is its first track).
The life of Jesus is seen through a different lens, that of apocryphal Gospels. Stripped of the most dogmatic facets of the story, what remains is a very humane story, about both love and pain.
People offering salvation might have much more down-to-earth motives than the supposedly spiritual ones. Yet believers still come in scores.
Lingua della canzone: Inglese
The stark comparison between an all-good God, and the evil in the world - or even just random unfair tragedies - leaves little room for believing. Unless He has a very sick sense of humour.
The concept of "Jesus" can be taken literally, as a deity, like religion does.
But it's much better to take it as a "verb", as a metaphor to spur people to be good to others, leaving all metaphysics aside.
Lingua della canzone: Spagnolo
It's close to impossible to believe in a god, when all around you, you see injustice and hardship. It looks like god has chosen to side with rich people, not caring about the poor.
The Science Museum in Florence has Galileo Galilei’s middle finger on display. This sort of laical relic is a perfect symbol for science and reason against religion and faith. So, in the song, Galileo’s devotees organize a sort of procession in support of science, carrying the finger with them, as if giving the finger to dogmatism.
Lingua della canzone: Italiano
A sarcastic song towards religious preachers who go door by door trying to convert people (or just take money from them).
In Italy, it is a quite common to have "testimoni di Geova" ringing your doorbell for this exact reason.
This is adapted from the last will of Jean Meslier, a French parish priest from the 1600s-1700s, who denounced the collusion of the Church with tyrants, nobles, and others taking advantage of the people. He was a priest and kept quiet while he was still alive, to avoid being tortured by the Inquisition.
It’s so much easier for people with a strong belief, never having to doubt themselves, and always having someone to call for help or to blame for what’s wrong.
Sometimes atheists wish they could be so sure, and meeting God face to face would provide some certainties.
What if "God" was not some higher entity, and it was just each and every fellow human being, to be respected and cared for?
A fast-forward history Earth’s life, from the planet’s coalescence through to our time.
Lingua della canzone: Italiano
A reflection about the misuse of the concept of God and the way it’s usually declined into religion.
Lingua della canzone: Italiano
An attempt to cope with the fear of dying, without having to resort to the religion concept of an afterlife.
Lingua della canzone: Inglese
You don't need to tell yourself lies about the universe; knowing that everything must come to an end, doesn't take anything away from the beauty of living.
Lingua della canzone: Inglese
A rejection of the traditional role that religion imposes onto women.
Lingua della canzone: Inglese
Most people outgrow their childish fears and beliefs in supernatural creatures. Atheism is just taking one step further.
Lingua della canzone: Inglese
A harsh criticism of religious people who claim for themselves the right to pass moral judgement on other people.
Lingua della canzone: Inglese
You can be extremely grateful for being alive even if there’s no higher power to thank for that.
Lingua della canzone: Inglese
