Update: There's now an efficient method of adding VA's album. Please refer to this annotation for more informationHey y'all... don't delete this page!It's a sandbox page to create Various Artists albums!

Let me explain:

So, a big problem on Genius is Various Artists albums that end up having the wrong artist, usually the first artist that got added to the album, or, worse, there's a dozen different albums, one for each artist on the album
Here's one, for example
Here's how to make a proper Various Artists album

To start, look for the Missing Track Info section on the right column of this page
In the Album(s) field, enter the name of the album, scroll down to the "Create new..." entry, and select it
Click "Save," and the album will magically appear underneath the fields with the proper Various Artists attribution. Click on it to view the tracklist. It's time to do some editing!
On the new album page, you will see that this sandbox page is part of the tracklist. We don't want that, so click on "Edit Tracklist" and then the X next to the song to get rid of it
Now you can add the songs that should be included in the album, drag them into their proper track order, then click "Save."

Also, for more Genius IQ, don't forget to add a proper album bio, and click on "Edit Album Info" to add the release date and upload the album cover

Finally, make sure you delete all of the duplicate albums. Use the Search feature on Genius to make sure you find them all. To delete an album, click on the "Delete" option from the "More" dropdown
That's it! Voila! A brand spankin' new Various Artists album!
