+
+## About
+
+Musescore Pro ($6.99/mo) is required to download sheet music from musescore.com recently. (However, a few months ago, it was free to download.)
+
+The Musescore company said that this is about copyright and licensing. They must pay to the copyright owners.
+
+Many musics on musescore.com are already in the **Public Domain**, that means either the author posted them in Public Domain, or the author has been dead for over 70 years.   
+Do they need to pay to those composers who died hundreds of years ago?  
+*Update: sheets in Public Domain are able to be downloaded without Musescore Pro now, but we still need an account to access them.*
+
+Also, there are many sheet music authors on musescore.com who created their own songs and posted them under [CC-BY-**NC** (Creative Commons Attribution-**NonCommercial**) License](https://creativecommons.org/licenses/by-nc/4.0/).  
+Is it illegal that they sell them for **profit**?  
+*Note: Putting ads (to sell Musescore Pro) on the website also means to generate revenue.*
+
+This is absolutely not acceptable, and the only purpose is to profit from stealing.
+
+There is an article on their website: [Score download becomes a part of the Pro subscription](https://musescore.com/groups/improving-musescore-com/discuss/5044610)
+
+## Installation
+
+This script is available as a [Userscript](https://en.wikipedia.org/wiki/Userscript). To use this Userscript, you need to first install a [user script manager](https://greasyfork.org/en/help/installing-user-scripts), like Tampermonkey.
+
+Install from [Greasy Fork](https://greasyfork.org/scripts/391931)

+This repo is also available on IPFS to avoid DMCA takedown.

+## About DMCA
+
+To the Musescore company:  
+If you want to DMCA take down this repo,  
+Could you imagine that your website is taken down because you disobey the principles of Public Domain and Creative Commons?
+
+PS: There is no problem that you get money by doing piano tutorials.
