No, currently you can't preview the music mood before the video is generated. Zebracat automatically picks a track that best matches the mood you selected.
But don’t worry, after the video is created, you can change the music easily inside the editor.
Just click the 
Music tab on the left sidebar, and you’ll find categorized music options like Energetic, Playful, Happy, and more.
You can play different tracks to preview how they sound and choose the one you like before exporting your final video.
