Youtube cracking down on music videos?

Has anyone else seen music videos get removed or restricted to viewers outside of the US? I am wondering as it seems a lot of videos that are not uploaded by the official music channels are getting removed. I'm just not sure if its Youtube staff or something else. Any info would be nice.

I don't know if this answers your question, but I've noticed that videos that have the lyrics to the song as it plays never get taken down.

The big company accounts can pretty much auto flag your vids though

Yeah thanks I didnt know they could take them down like that. Its interesting before there werent any problems but now a lot of videos that are promoting ringtones are going down. It seems like Youtube is noticing them more now.
