Hi,
I'm Jurgen, volunteering for Software Freedom Day
<https://softwarefreedomday.org>. Some friends at the FSF recommended me
to reach out to your team with this:
For Software Freedom Day (Sept. 16th), the team Software Freedom Day
team creating the best Software Freedom Song, can win a nice prize
donated by MuseScore.
I think it would be cool if someone using Lilypond would create a song
about Software Freedom!
You can find more details here:

You can join us to chat on Matrix
<https://matrix.to/#/#SoftwareFreedomDay:matrix.org> if you have more
questions.
Hope to be hearing from you!
All the best,
Jurgen
