This video is exactly as described in the title: a sound check. I'm planning to create a series of new videos using artlist.io services for music. However, before I proceed, I'm curious about what happens when I transition a video from 'unlisted' to 'public'. Essentially, I'm conducting a test with this video, which requires me to make it public. I'll likely remove it later once I gather the information I need. But since you're here, I wanted to let you know that I'll be producing movement videos again soon.
