Your mashup was taken down for copyright infringement
Since a mashup is based on other creators' tracks, you'll need to make sure that the copyright owners of the works you included in your mashup are fine with you using them in your upload to SoundCloud, even in their edited form. If you created your mashup based on tracks you have downloaded or found from other online sources, you will still need the content creator’s permission to upload it to your account - crediting the original creator does not count as permission.
If you are able to provide proof that you do have permission from the originals’ rights holders to publish their material in your mashup on SoundCloud, our Copyright Team is happy to manually review these permissions and reinstate the track onto your profile.

I uploaded my mashup under Creative Commons, why was it still taken down?
Creative Commons is a non-profit organization that has drafted a set of copyright licenses that may be used by any creator for any of their content. With Creative Commons licenses, creators have the choice to give up certain exclusive rights normally associated with copyright, while retaining others.
Although you, as the creator of the mashup have chosen to give up certain of these exclusive rights associated with copyright, the original creator of the track you used still owns the copyright for that part in your mashup, and you will need their explicit permission to publish your track on SoundCloud.
I uploaded my mashup for non-commercial purposes, doesn't this qualify as fair use?
Fair use is a legal doctrine that primarily exists in the copyright law of the United States. Fair use limits the exclusive rights granted by copyright and allows the use of copyrighted material for certain limited purposes only, without requiring permission from the rights holder and depending on the exact use of the original work to be determined on a case by case basis. Purposes recognized under fair use may be such as criticism, comment, news reporting, teaching and similar activities.
However, uploading a mashup for non-commercial and promotional purposes to SoundCloud does not fall within the fair use exemption.
