Can I add a song to a video I made and put it on You Tube?

Without breaking copryright laws. I see people putting songs on there home videos all the time but is it bad to do.

it is possible, but you'll have to make a new video and stick them together. But, its not all that bad, all you have to do is divert most of the attention your original video is getting to the new one by posting comments about it on the original video. Your the author, they will listen.

Some sites (yahoo) appear to have built-in censors to prevent the citation of certain sources.

Know that my response has been *severely* limited by a "999" error.

Any posting on YouTube (or other sites) of another person's work - audio or video - is technically a violation of copyright law.

Lots of people do it, that doesn't make it right. Very few people get caught or reprimanded, I think - however, if the copyright owner should see your video, they have the right to contact YouTube, prove they are the copyright holder, and have your video removed.

If the copyright holder never sees it, you may be in the clear - but repeated copyright violations could cause YouTube to take action against you by disabling your account.

For more information, check out the Digital Millennium Copyright Act. All web-sites have to abide by its terms, and many will reference this in their terms of use.

You should read YouTube's Terms of Use - by registering with them you must agree to abide by their terms, which includes not posting known copyright violations.
