OpenBSD 7.2 did not have a release song, but OpenBSD 7.3 did.

Likewise there has been several other versions that did not have songs either in the past.

So probably there will be more songs in the future too, even if not every release has a song.

I still miss buying CD sets. I understand why the project doesn't do it anymore (lots of effort and time, similar to why VAX was dropped), but it sure was fun getting them in the mail and using official discs to install.

Also looking forward to artwork merch but that's still for 7.3 on their shop, maybe it will be updated in a few days?
