Hi there,

The question you need to ask yourself is: Who do you want to proof your ownership of the commercial license to and why?

Essentially, your purchase of a commercial license is a legal contract between you and MAGIX, which entitles you to exploit the soundpool content commercially. MAGIX knows whether you have or haven't purchased the commercial license, because they have the relevant Catooh and/or ProducerPlanet/in-app store transactions on file. So, they'll just need to know the relevant account and/or order numbers, and will be able to verify that you purchased the commercial license.

Third parties are generally not interested in whether you fulfilled your licensing obligations towards MAGIX or not. They cannot know whether or not you own the commercial license for the soundpool content used in any given song. Also, nobody would be able to know this simply by *listening* to your song, including MAGIX staff.

Now, you didn't ask this question, but it's a common question we receive at MAGIX customer service, and it might be the motivation behind your question: What about receiving (erroneous) copyright violation strikes on YouTube or similar platforms? The answer is that this is completely unrelated to whether you have a non-commercial or commercial license for the content you used, and having a commercial license isn't going to protect you against something like this happening. Again, YouTube doesn't care whether you fulfilled your licensing obligations towards us. The only basis for the copyright claim is that some algorithm or person detected a similarity between your song and another song. (Leaving aside the fact some people are also known for making willfully incorrect copyright claims against other people on YouTube.) This situation doesn't come as a big surprise if you used content that was possibly used by many other people in their works as well, some of which may have used it earlier, and some which may have distributed their music commercially through bigger digital distribution networks. However, MAGIX is licensing the content on a non-exclusive basis, so you're well within your rights to also use that same content in your songs. So, how do you defend yourself against this kind of erroneous claim? You use the appropriate feedback channel for disputing incorrect claims on the respective platform. You escalate the issue to whoever can check and verify that your song is indeed not identical to the other party's song. Pointing out how the song was created and that this might explain the use of the same loop in both songs probably won't hurt.

Well, hope this info helps, and maybe is what you were looking for.
