There has been some discussion about the intention of the different PV types.

The current policy is that the “original” PV type should be used for the first authorized PV for a particular song. In this case authorized means that the person uploading the PV had permission to do so. The reason for this requirement is that original PVs are promoted as official, and displayed separate from reprints and “other” PVs. Promoting PVs that use content without permission as official might insult the creators of original content, which in turn makes VocaDB look bad, so we want to avoid that if possible. We’re doing this to support the creators, whether they’re doing it as a hobby or professionally.

Maybe you’ve seen the Suggestions, requests, features to improve the website thread on the site. Related to that, I want to explain a few things.

I consider VocaDB a large, mature website. It’s feature complete in the sense that it has everything that I originally planned it would (and more), and there aren’t any major limitations/problems with editing or browsing the website. Of course a website needs to evolve, and there’s always something to improve or add, so it will never be completely done.

As I mentioned in an earlier post, being able to rename tags was just the first step. Since then I’ve removed the limitations on naming tags, and since yesterday, tags can now be translated as well, like other entries. This means that for example names of anime series such as Attack on Titan can be entered in original language, Romanized and English. This should be good news especially to our Japanese users who aren’t limited to English names in tags anymore.

Another year is over in the world of singing synthesizers. Vocaloid scene spreads around the world and VocaDB grows as well. The editing activity on VocaDB has been increasing steadily. I’m happy to say that it’s been pretty good year for VocaDB, and it’s all thanks to our editors!

Honestly, thanks to everyone who contributed their time to make this the most complete and accurate Vocaloid discography database possible – let’s make the next year even better. It’s not just about the songs and albums being catalogued, but also translating titles and also smaller things such as rating songs.

Some numbers: in total, 22 500 new songs and 1 330 albums were added to the database. 790 new users joined. 657 675 visits by 360 403 users was recorded by analytics!

The most popular song on VocaDB, with a rather wide margin, was News 39 by Mitchie M with 63 total score.

The most popular album was Lamento by calvi with 22 ratings and 4.9 (out of 5) rating average. That album is free to download by the way (which is probably a reason why it was so popular).

Thanks again, and happy new year 2016!

Related to the upcoming tag renaming feature, all tag references in the web API will be changed from tag names into tag IDs in the near future. This applies to both query parameters and values returned by the API.

So, instead of it will be

Renaming tags

For the past month or so I’ve been working on a feature that has been requested multiple times: being able to rename tags on VocaDB.

As you probably know, currently tag’s name is determined when the tag is created and there’s no way to change it afterwards. This is because, unlike other entries on VocaDB, tags were originally identified only by their name. They did not have a numeric identifier (Id) at all. The reason for this was because I wanted to keep tags as simple as possible, but it turned out to be a design error which I am slowly fixing.

There has been some confusion regarding how to handle upcoming voicebanks that are still in development, mostly Crypton Future Media’s (CFM) new voicebanks for Hatsune Miku and the Kagamine twins.

If you’ve been actively following the Vocaloid scene, you’ve most likely heard of a significant number of Vocaloid PVs on YouTube suddenly becoming unplayable in USA, because of YouTube Red, Google’s subscription based service for watching YouTube without ads. Major Japanese labels have not signed up with Red, so YouTube disallowed playback of those videos. It’s uncertain how long this situation will last and whether it will spread to other countries when Red is released there. How is this related to VocaDB?

Videos being taken down from YouTube is nothing new, although most of the time it’s been about of copyright-infringing reprints. A couple of major YouTube channels providing subtitled Vocaloid PVs have been taken down as well. The default service for uploading Vocaloid PVs is of course NicoNicoDouga, but Nico has its own problems such as poor streaming performance outside of Japan, lack of SSL support and their mobile app being limited to Japan only.

If you ask me, all this proves is that you shouldn’t put all your eggs into one basket. Many artists are already uploading their songs onto multiple streaming providers, usually NicoNicoDouga and YouTube, sometimes SoundCloud and piapro as well. That’s really good, because if and when there’s a problem with one of those services, the fans can just use another service. And to bring all those copies of songs together there is VocaDB.


VocaDB is agnostic regarding to streaming providers – we support all the major providers and it’s possible to add more (like DailyMotion) if needed, as long as they have APIs. Switching between different providers is a simple matter – it’s even supported by our embeddable player! This is of course on top of the other great features we have, such as highly advanced search filters. At this point I should mention that since we want the artist to get as much of the traffic as possible, all of our players prefer showing the original videos (as uploaded by the artist) over other copies such as subtitled versions made by 3rd parties.

You can make use of VocaDB’s song lists to include songs from multiple sources. It’s highly likely that not all of your favorite songs can be found on one video website, but that’s not a problem as long as the song has been indexed on VocaDB.


If the song gets deleted from one site, for example if your favorite subbing channel is taken down, don’t worry, the entry still remains on VocaDB and you can use the other streaming services to play the song, as long as at least one copy exists. If the deleted song ever gets reuploaded, it can simply be updated on VocaDB thus fixing it in all playlists where that song was present.

VocaDB is a unique service in the sense that it collects Vocaloid/UTAU PVs from all possible sources – NicoNicoDouga, Youtube, SoundCloud and others – into a database that can be queried and searched in very flexible ways. We also have a huge collection of those PVs in our database – over 70 000 and growing daily. This allows us to create reports that represent the overall Vocaloid scene while not being limited to a single service. You can check those yourself on our statistics page.

VocaDB features

I wanted to make a post showcasing some of the most useful features of VocaDB. This list is in no way comprehensive, but should give a good idea to someone who might not know about the site yet.
