You might enter any year in the release year tag but it is only written into the song if the value is 1900 or higher.


The earliest known invention of a phonographic recording device was the phonautograph, invented by Frenchman Édouard-Léon Scott de Martinville and patented on March 25, 1857. It could transcribe sound to a visible medium, but had no means to play back the sound after it was recorded.


Thomas Alva Edison conceived the principle of recording and reproducing sound in 1877 as a byproduct of his efforts to "play back" recorded telegraph messages and to automate speech sounds for transmission by telephone.


1900 is a bit to high as a lower limit.

Year null

Once a year has been entered WMP wants a number (=> 1900). You can't clear the field.
