Some authoring software and online music services allow you to display some of the META information that is inside your files. Extremely few are capable of displaying all of it. Hence the importance of hiring a professional to do this.
If you have the required tools and the professional skills to access ALL of the metadata of the file yourself, then sure, you could. But at only $5 a song/video, why would you want to?
Save yourself the time, work, and risk of missing some and allow our ISRC professionals handle the file verification for you. You can order right here.
