"Attribution" means that if you distribute any Karlheinz work, or a derivative of that work, then it must be credited to Karlheinz.

To properly attribute a Karlheinz work, you must do all of these:

• It must be attributed to Karlheinz.
• You must provide a link to my website: http://www.khznoise.com .
• You must cite the original title of the work, e.g. "the track Eye, from the album Brute." (If you are using material from several songs on one album, simply citing the album is sufficient.)
• If it's a derivative work (see below), you must present it as such.
• Also if it's a derivative work, you must not imply that you, or your work, is connected to, sponsored, or endorsed by Karlheinz.

Most of these requirements are actually put in place by Creative Commons. For details, see "How do I properly attribute a Creative Commons licensed work?" from their FAQ.

All international licenses - Creative Commons included - have this requirement. The reason is that most countries have "moral rights" (the U.S. being an exception), and attribution is considered the most important of these. "Moral rights" are considered fundamental human rights, so they usually cannot be waived, even with the consent of the artist.
