InSoc Beat Mutation Syndicate | Information Society: “The Insoc Beat Mutation Syndicate provides you with an opportunity to make your own remix of and InSoc song. Using the DOWNLOAD link to your right, download a Remix Pack (either as a zip file or as individual .mp3’s) and create your new musical masterpiece. When you’re finished, use the UPLOAD link to send it back to us. If we like it, we will post it here and/or on our myspace page.”
Their license doesn’t seem to specifically forbid non-commercial posting of remixes based on their remix packs. Overall the licensing looks rather remixer friendly, i.e. less restrictive than for example realworldremixed.com. However the licensing is not specifically creative commons based, like for example aminortheory.com.
