# Tags editor
Ultarstar stores metadata about the song (e.g. artist, title, tempo) in the form of tags. Different versions of the game may understand different sets of tags. The common ones are described in the [tags ](https://karedi.gitbook.io/karedi/next-level/txt-file-format/tags)section.
Day to day users do not really need to concern themselves with tags when working with Karedi. The application lets you change the standard metadata values from the menu hiding the technical details of the txt format.
## Editing tags values
To learn how to edit song metadata in a convenient way from the menu, please go to [this page](https://karedi.gitbook.io/karedi/next-level/editing-tags).
## Displaying tags values
If you are a more advanced user who likes to work on tags directly you can see the current list of tags with values in Tags editor.
Tag editor is located above the [*main editor*](https://karedi.gitbook.io/karedi/user-interface/middle-components/main-editor), on the right side. By default [*lyrics editor*](https://karedi.gitbook.io/karedi/user-interface/upper-components/lyrics-editor) tab is selected. To manage tags you need to switch to the second tab by clicking on the *Tags* tab caption.
Here you can see the full list of currently defined tags:
## Adding a new tag
You can add any tag that is not already present in 2 ways:
1. Go to menu *Tags* -> *Add New\...*
2. Right click somewhere in the tag editor and choose *Add* option from the context menu
Either way you will see a popup in which you can add any tag you want.
If given tag already exists, its value will be simply updated.
Standard tags will be suggested and validated so for example if you choose START tag, which must be a number, you won't be able to input letters as a value.

The set of suggested tag keys will depend on the song's [UltraStar format version](https://karedi.gitbook.io/karedi/next-level/txt-file-format/format-version) defined by VERSION tag.

Some tags like e.g. LANGUAGE have value suggestions:
