+	# In the past, most scott's music on soundcloud has opus format, some are
+	# mp3 and some are m4a with aac. At maybe February 2026, I can't download
+	# scott's music from soundcloud with yt-dlp with this cli. Later on at May
+	# 2026, the issue somehow fixed. But I noticed that yt-dlp can only
+	# download most scott's music on soundcloud in m4a with aac. This cause me
+	# redownload a lot of music in m4a. I prefer opus because it is better and
+	# take less space. And I want yt-dlp to not download already downloaded
+	# music files. So I decided to use `-x --audio-format opus` to convert all
+	# of them to opus. The trade-off is that converting lossy to lossy is bad.
