Not at all.

The license conditions grant you automatic permission to use Karlheinz material. If your specific use is not covered in the license, it just means that you must get permission for that use, the same as you would for any other copyrighted work.

If it is music that I released myself, then you should contact me directly. If it is released through a third-party label, you should also contact that label. Their website should be displayed on the release page, but if you're having trouble getting hold of them for some reason, then writing me is a sure-fire way to resolve the issue quickly.

Whether I grant permission, and for how much money (if any), depends upon the usual factors that help artists decide who is "entitled" to their works:

1. How deep your pockets are.
2. How much I've had to drink.
3. How much of a chance I think I have of sleeping with you.
4. How convincingly you cry. Seriously, you should bone up on this. Combining this with #3 will pretty much guarantee your use of both my artistic material and my physical form.

Of course, the only rights I have are the rights granted to me under U.S. copyright law. That means all copyright exemptions apply, such as statutory royalty rates and fair use. You should probably look those up.
