When your upload gets stopped by SoundCloud, there is a process for them to review and approve. It looks like this:

"If you are the copyright owner of this content, if you have rights holder permission to share the content, or if you believe a mistake has been made, please file a dispute here: [your-soundcloud-link]"

What you will need to do is respond to the Soundcloud copyright notice with the Talenthouse Creative Invite URL and the links to the Stems provided.

SoundCloud are very quick to approve the file once the correct information has been provided for them to confirm.
