To delete a track from PlayIt Live, go to Manage > Tracks which opens the Manage Tracks window. In the track list, locate the track you want to remove and click the Delete button next to it. A confirmation window will appear to ensure you want to delete the track as this action is irreversible.

You can also delete multiple tracks at once by selecting them using Ctrl+A to select all tracks or holding Ctrl while clicking individual tracks, then pressing the Delete key. Remember to click Apply or OK to save your changes.

Note that deleting a track only removes it from the PlayIt Live database - it doesn't delete the actual audio file from your computer.
