> Removing individual links makes sense--if someone filed a DMCA request with Dropbox for a song and it ended up getting removed from my Dropbox as well that would be ridiculous.

Dropbox has a very clear concept of private files and public files. If a DMCA request was issued for a file you're storing in your public folder, I would certainly expect Dropbox to remove all instances of that file in all public folders on all accounts.

You seem to be saying that if I write and record a song and put it on a dropbox public folder, then issue a DMCA takedown for another user who has copied my files, dropbox should delete my files as well.

That makes no sense, whatsoever.

What if the file in another public folder was held by the owner of the copyright, or someone else who had license to distribute it?

...then that exceptionally rare person will be inconvenienced in the process of correctly dealing with the significantly more common case. In either case it should be relatively easy for them to reacquire the file, if needed.
