This issue usually comes from the source of the file and how it’s converted. Mp3Juice is one of those tools that pulls content from different places, so metadata isn’t always perfectly transferred. I’ve noticed that sometimes you get clean and accurate tags, and other times you need to edit them manually. There are apps and software that can help fix metadata quickly, especially if you have a large music library. While it’s a minor inconvenience, it’s something to keep in mind when using free download tools. Over time, you learn which sources tend to provide better results.
