“It’s been a long time since Track 10 was released on Soundcloud – finally we got the opportunity to continue our work on this project. One more track is in mastering right now and will be released soon.”
Track 08 and 10 are not CC-0 but CC-BY-ND due to the vocal samples. The rest is CC-0.
CC-BY-ND – the ND means “no derivates”, and that means you cannot create new music from these pieces. You can of course use it in your commercial video project, layer other audio on top and monetize that video.
