Hi,
Plenty of things like this happen in the Wikimedia world every day, but as a music lover I'm especially happy about this one: The Open Well-Tempered Clavier project was completed yesterday with the public domain release of all the music files, and it's already on Commons: https://commons.wikimedia.org/wiki/Category:Open_Well-Tempered_Clavier
In case you didn't know, The Well-Tempered Clavier by Johann Sebastian Bach is one of the most popular and influential works of European classical music. The Open Well-Tempered Clavier is a project to record a complete performance of this work and release the music files, as well as proofread digital sheet music, to the public domain. It was crowd-funded through Kickstarter.
The Well-Tempered Clavier is kinda like the "Dark Side of the Moon" of classical music - if you listen to classical music, you likely own a recording of it already, but since we are free culture geeks here, I'm sure that you'll appreciate having this copy, too.
It's public domain, so download, listen and share as much as you wish, but you may also want to show your support to the people behind this project by downloading and naming your price through Bandcamp or purchasing a CD: http://welltemperedclavier.org/
My personal thanks to the people who develop Pywikibot, thanks to which uploading 48 huge files to Commons was easy (and indeed, possible - one of them is over 100MB).
(Also, tomorrow is Bach's birthday according to the Julian calendar.)
