Some confusion about licensing terms here. The license you've selected is GPL, the copyright notice text describes CC-BY-ND, and the Q/A blurb describes a proprietary -NC license. 

It is fine to link to other premium content for which your customers can purchase additional content, but the content here on OGA must be under one of the available licenses. It must be clear which license are being applied to the content here and with no terms that conflict.

-ND licenses are not accepted on OGA. -NC licenses are not accepted on OGA. Proprietary pay-to-play licenses are not accepted on OGA. Although it is fine to apply such licensing to externally hosted content, it should be clear such terms do not apply to the content hosted here.

Would you be willing to commit to the terms of one of OGA's accepted licenses, omitting the terms for others on this submission? I must mark this as having a licensing issue in the meantime, in order to protect your wishes. Let me know if you have any questions.

EDIT: Fixed, thanks!

Also, the Google drive link does not work...! 

The sample track is nice.

Links on submissions with potential licensing issues are disabled to prevent the proliferation of assets that the author may not wish to be distributed. In this case, you clarified the license and do indeed wish those assets to be distributed, so the link was re-enabled along with the downloads here. :)
