Near the top of song pages there's a section where it will show other songs based on this song (covers, instrumentals) or the reverse. I've added a new section, "More songs from the same creators". It matches songs based on having the same people in the same credited roles. It scores some things particularly high (like Arrangement) and some things particularly low (like Vocals). It then ranks them by score, randomizing order where there are ties, and presents the top 5 results. It's also set to not give itself as a result, or songs which would already be in one of the two above sections. It also won't list instrumentals in general.
Another big add is all the Petit Best albums have been added. Though mostly compilations, since they include remixes, occasional new songs, or songs from other obscure sources not already covered in the database, quite a few new songs were added to the database alongside them.
Yet another big add is I finally went through to fill in more song lengths for songs that were originally added before the current official discography pages were set up. There are still gaps, but where there were over 700 songs without lengths, now there are only 200.
One of the differences you might notice is in the order by which people are listed in various locations. As far as the database is concerned Seniority is largely based on date of a person's first credit, but in cases of ties (such as when a generation of several members debut on the same single) in the end it would come down to the happenstance of what order I typed them into the database. Now it can use birth date for these ties, which basically matches what they do in the real world. The member order on a group page now also uses the birth date and ignores the larger Seniority value. This prevents situations like Berryz Koubou ordering being out of whack due to members' prior work in ZYX or 4KIDS.
I've tried to make it order properly when multiple groups perform together too. First group seniority, then how the individuals would be ordered within the group. There are always unusual circumstances and it would be difficult to make sure every situation sorts out perfectly, but I've got it working on the extreme case of Busu ni Naranai Tetsugaku so I'm pretty happy for now.
Another addition is that when viewing songs, the list of vocalists will also show their age at the time of the song's release, as well as an average. Of course the songs are recorded earlier than that, but what are you gonna do.
