In the world of music, the hits keep coming

Are we running out of new music?
The Beatles have got a new single at number one and The Rolling Stones have brought out an album, surely I must be in some sort of time warp. Have I been transported back to the sixties via some sort of time tunnel or maybe this is a dream.
No, apparently it is true and I am not imagining it, thank goodness for that.
The thing is and what I have come to realise is that music never dies, it sticks with you and just when you think you have heard it all, something new hits your ears.
Music is amazing, given there are only 12 different notes in western music and with the millions of different songs and tunes that exist you would have thought that all the possibilities would have been used up, that nothing new could be created. Seemingly this is not the case.
Spotify already have more than 70 million songs in their catalogue, but there is still the possibility of endless new music being added. That’s not possible I hear you cry, but it is. Now I am no musical expert but if you calculate the number of possible melodies within an octave (the  interval  between one musical pitch and another) and add in the gaps between the notes and the tempo it can be played at, that would be a big number, someone calculated 36 digits, that is a lot of noughts!
There have of course been some high profile cases of copyright infringement, but even when you listen to the songs in question there are always differences even if the result of the case says not. Many songs use the same chord progression. A favourite is A G Cm F, for example Let it Be by the Beatles and Let it Go from Frozen use that progression and I do not think anyone will be mixing those two up anytime soon.
Seems therefore that we will not run out of new music anytime soon. Maybe we will run out of truly innovative music as we tend to like what we like, the stuff we are used to. This could be why the bands of the past still have a place in the charts today. I guess creativity could be limited in the future, but as music is so important to us all, I don’t see it drying up anytime soon.
Having seen the figures for Spotify, I am wondering if the Torbay Hospital Radio library is big enough to cope with the volume of tracks out there. If new stuff is released by Elvis, Prince or Bowie, we are going to need somewhere to store them.
