Taken down Remixes/Mashups

I do not know many remixes/mashups which have been taken down, but I have managed to find a few.

'Both my We Found Love and Titanium remixes were taken down off soundcloud for copyright.'

I have heard from a few people as well as read that SoundCloud takes down copyright music and videos, therefore both the remixes were taken off SoundCloud, but they were moved to YouTube and so far are still there!

Here are the links:

Rihanna - We Found Love (Eos Remix) - http://www.youtube.com/watch?v=xwdin_Vgzjc 

David Guetta - Titanium (Eos Remix) - http://www.youtube.com/watch?v=qiM1pk1ffxU

Many video and audio remixes are taken down because of 'copyright reasons'.
Video servers, such as YouTube, take down videos which they believe (or rather their system) has copyright in them. Therefore many music and video remixes, having material copied from either a song or video can be taken off.
Also, mashups can be banned because they are offensive.

Usually, once a remix is taken down, it will be uploaded onto a different server, so it won't die and people will still be able to find it.

I personally have had a few problems with the YouTube EMI COPYRIGHTS. They have either muted my video, or banned it in certain countries... very annoying!

If anyone does know of any remixes/mashups (video or audio) which have been taken down, please tell me about them in the comments section.

Thanks for reading :)
