CCMixter is all about freedom to share. However, the extent of those freedoms has always been up to you. You are free to choose: whether your music can be freely used in commercial or non-commercial settings.

Anyone who uses your music in a way that goes beyond the CC license has infringed your copyright. In some cases, it is an honest mistake. Increasingly, we are finding instances where it is not.

Because Creative Commons licenses are not just compatible with copyright, but depend on them, US copyright law gives you tools to easily notify someone who is infringing on your rights, and you do not need to be an American to take advantage of that, if the infringer is American.

Now bearing in mind that I am not a lawyer, US law permits you, the copyright holder, to issue what is called a DMCA Claim. Basically, this is a signed letter where you identify the song that infringes your rights, and ask them to take it down. An electronic signature is valid, but Google services generally require a physical signature – so be sure to scan your signature and use that (or take a picture of it with your iPhone and crop it in Photoshop.) You will want to send the notice not only to the infringing site, but if they’re being hosted on or are using some form of communal hosting (like Blogger, Youtube, or Wordpress), send them a copy as well.

Your note could go something like the following.

I have a song on Mixter called Slow Motion dream. I used samples from Csouls ’ Somebody Help Me ” I always use the attribution. I think I may have found someone using samples from either my version or Csouls and not giving any credit to either of us or CC mixter..Definitely not using the attribution…I found this on one of the sites I am on…Here is the link to this Artists page and it is the second Song. The bpm has been speeded up and I may be wrong but I dont think so… http://www.liquidaudio.org/... Please let me know
