Hmm, that's strange.

The Looperman Terms and Conditions state that by uploading this loop, it's open to the public under a royalty-free license - that is anyone can do almost whatever they want with it. You can find them at https://www.looperman.com/help/terms and the specific section is "Rights Granted By You When You Upload Content To The Loops Area". This also means that as far as I know, there is no "authorisation" I can provide to either you or Spotify as it's not supposed to be necessary.

It's entirely possible that someone else has also used this loop, made a track with it and uploaded it to Spotify, which has led to your track being incorrectly flagged as breaching their copyright. If that is the case, then my suggestion is to email Spotify support and explain that this sample is royalty free, include a link to the Looperman Terms & Conditions page and a link to this sample page.

Absolutely my friend! I've sent you the link via PM.

No problem, just link me when you're done. I like to see other people's work. :)
