Changes made aren’t showing in iTunes
If changes you have made to your RSS feed aren’t reflected in iTunes, first make sure that your feed is valid here.
Feed isn't valid
If your feed is not valid, then iTunes cannot read and show the changes you have made. If your RSS feed is showing error messages, please go to our Help Center article here for more steps on how to make it valid again.
Feed is valid
If your feed is valid, then this means that iTunes needs to refresh its cache and recognize the changes you have made. As a hosting platform, SoundCloud has no influence on how fast iTunes updates its store. Generally, iTunes updates within 24 hours. If you do not see your changes reflected within 24 hours, you will have to reach out to iTunes directly.
