How do I report to Yahoo if the Yahoo Search Results give wrong destinations?

Today, I searched for "free online radio stations" and all search results returned different links. I got the link for MTV Radio - a href="http://www.mtv.com/mtvradio" rel="nofollow"http://www.mtv.com/mtvradio/a but everytime I click it, it goes to a href="http://www.merriam-webster.com" rel="nofollow"http://www.merriam-webster.com/a so, I'm not sure what happened ... if MTV's site has been hacked or something. Help?
