Adele’s new song “Hello” has been a phenomenal hit around the world but opinions are divided about whether the song itself is deserving of such success – or if it’s simply the result of clever marketing to a hungry fanbase. We asked five experts on music theory and analysis to give their opinions on what’s responsible for the massive success of “Hello”.

Since its release on the 23rd October Adele’s first single in three years has been breaking digital records all over the internet. It clocked up one million YouTube plays per hour in its first two days of release and two people were Shazaming the track every second in its first 24 hours.

“No single has ever been Shazamed so much in its first day”

On Friday it was unsurprisingly number one in the UK chart – the biggest number one for three years, in fact – and it has now become the first song to sell over 1 million U.S. downloads in a week.

The opening of the song is being described as “iconic” by the BBC and the song seems to have moved its listeners to tears in an inexplicable way.
