Youtube music videos - are the artists prohibiting usage?

Question

I had loads of videos listed on my favourites that now seem to be either "unavailable", or seem to have just disappeared from my list. Has there been a huge amnesty on these videos recently? I had access to them only about 3 weeks ago.
