The question Notes not adding up to time signature, with weird white oval note turned out to be related to a piece of Punjabi Christian sacred music.
In looking to add an appropriate tag to the question, I first thought to look for "sacred", which, to my surprise, didn't exist. On the other hand, church-music does, as does hymnody, both of which I found only after doing a search for "sacred" and seeing the tags applied to questions in the search results.
I chose hymnody, since it's closest, but not all sacred music is hymns, and it certainly isn't all "church music".
I suggest replacing both tags with the more musically and pluralistically inclusive sacred or sacred-music.
There is highly relevant discussion in "church-music" tag -- Do we need it, and if so, what does it cover?
