Background music can change how people feel when they watch an ad video. Ad video means a short video used to promote a product or service. Music can make the video feel happy, serious, or calm, depending on the sound. The problem is that loud or annoying music can distract from the message. I think soft music that matches the message works better than random popular songs. The main goal is to make people understand the message clearly. What do others think about using music in ads?
