Eurovision 2023: the best of the first night, photos

Have you ever found yourself humming, vocally and in your head, the melody or lyrics of certain songs even when you don't want to, to the point that that musical tune can't get out of your mind?

Nothing to worry about: this experience happens to about 90 percent of people at least once a week, and at most it can be a little annoying not to be able to stop a melody that repeats incessantly in your head.

Here is what earworm is, what are its causes (and possible remedies) according to scientific studies conducted over the years: browse the photo gallery to learn more

What may have been the best-selling single in the entire history of music? This record belongs to an obviously very famous song, composed many decades ago but still very topical. We hear it every year, as do all the top 10 best-selling songs of all time.

The calculation has been split in two, due to the advent of technology, downloads and Spotify streaming, which have 'drugged' the market and made the previous charts truly obsolete. This calculation was therefore split between physical single sales and digital sales. Here we will only deal with sales of physical singles, and therefore you will not find the most recent songs.

This is a compendium of the best-selling music singles. The criterion for inclusion is to sell at least ten million copies worldwide. The singles listed here have been quoted from reliable sources in various media, such as digital journalism, newspapers, magazines and books.

Enough, after this preamble we won't keep you waiting any longer, your curiosity will already be tingling: here are the 10 best-selling physical singles in music history.

Who says that there are only guitars, pianos and drums? The world of musical instruments is very rich, varied and original.

In fact, there are instruments that are little known all over the world, but equally interesting both for the operating modes and for the type of sound they produce.

Some of these instruments represent variants of traditional instruments such as the flute or double bass, while others are totally original, born from the inventiveness and creativity of musicians, craftsmen, but also of scientists (for example Benjamin Franklin).

Here are some of the most unique tools in the world that you may not have known!

Roger Waters was a co-founder and historical member of the British music group Pink Floyd, in which he served primarily as bassist and vocalist.

Waters was also the historical author and creator of the underlying themes of some of the group's most famous albums such as "The Dark Side of the Moon", "The Wall" or "Animals". After becoming leader of the group, Roger Waters left band in 1985, pursuing a solo career.

A curious anecdote about a statement Waters made in the 1980s, in a famous interview with Times in which he had said, ""Atom Heart Mother", here is a perfect example of an album that should be thrown in the trash can and never listened to again. It's really horrible and embarrassing."

Music unites generations and hearts. While for many people listening to music is a private pastime, some want to share it with the rest of the world and experience it by dancing amidst the crush, heat, sweat and fun.

Music gatherings, or festivals, have become annual fixtures for now millions of young enthusiasts, who travel the world in search of the best and most spectacular date ever.

There is a veritable world of festivals around the globe, but there are undoubtedly some that have become more famous and important than the others, and that bring together the best artists in existence today. In this short gallery we show you which are the most beautiful and well-known events and festivals in the world.

Not just intros: songs sometimes make it to the top of the charts thanks to unforgettable, all-singing choruses. Making this list was NME, New Musical Express, Britain's historic weekly music magazine.

Three key elements were taken into consideration in making this list:

1. The ability of the refrain to move the listener

2. The ability of the refrain to make the listener sing along

3. The ability of the refrain to make the listener dance.

Here is the list of the most recognizable refrains: do you agree with this ranking or would you have changed anything?
