 After adding files to the playlist, the total playlist time is displayed in the top right corner. The duration of an individual file is shown in each row of the playlist in a white font, and beneath this figure the time since the beginning of the playlist is displayed in a smaller light grey font. This elapsed time figure can be used as a time check for voice tracks, although this option may limit the re-usability of the voice track.

 Fill out the smart block's **Name**, **Search Criteria**, and **Limit to** sections. The search criteria can be any one of LibreTime's metadata categories, such as **Title**, **Creator** or **Genre**. The modifier depends on whether the metadata in question contains letters or numbers. For example, **Title** has modifiers including _contains_ and _starts with_, whereas the modifiers for **BPM** include _is greater than_ and _is in the range_.

-Smart Blocks by default will not overflow the length of a scheduled show. This is to prevent tracks from being cut-off because they exceed the time limit of a show.

 You can also set the **smart block type**. A **Static** smart block will save the criteria and generate the block content immediately. This enables you to edit the contents of the block in the **Library** page before adding it to a show. A **Dynamic** smart block will only save the criteria, and the specific content will be generated at the time the block is added to a show. After that, the content of the show can be changed or re-ordered in the **Now Playing** page.
