All The Music

To date (2023) Damien Riehl and Noah Rubin have copyrighted over 400 Billion melodies. There may not be any tunes left to write, so what is a song-writer to do!

The Answer is simple: "Write your song"

Riehl and Rubin have not copyrighted every tune to stop composers from writing but to free them to write. They have placed all the tunes ('all the music') in the public domain for common use. It is early days with regards to how the courts are going to deal with this, but the hopeful result is that song-writers need not be in fear of being sued for plagiarism once their song is out in the world and (hopefully) making money. How can one be sued if the tunes are already in existence and are free to use by anyone? And as Riehl and Rubin are not going to sue the songwriter either, then they are worry free.

There must be some drawbacks?

If you want make the claim that you are the originator of that tune, and that you own it, then you will need to think again. As Toast theory also states, your song is not original, it can be traced back to the very first song ('This Song Sounds Like Another Song').

You might want to sue someone else for stealing your song. You might still be able to do this (bad people may really have stolen your song, that's quite possible), but it won't be the 'tune' itself that you will sue over but the 'song' (the law, eventually, will recognise a difference). Essentially, someone will have made a 'remix' or a 'cover' or a 'recomposition' etc of your song, but it's (probably) still your song.

Take a look at their website with the TEDx Talk (2019) and access to the legal arguments (note: not legal 'advice'!), as well as access to the tunes and software.
