A song is added to the database by being a top line thread, not a sub thread like when we add to the music room. Then it has to have the musiconleo tag so it is posted in that community (and we see it). It is then added to the database and when enough of one artist is there, we make a page. also we need artist name - song name for search.
Here is an example.
