youtube has changed for the better a little. They used to identify a song and shut off your sound totally (as you are worried). But now they identify the song, and add and for sale links in your description for you. (if the recordlabel/distributor/whoeverownsthecopyright has agreed to it). However....the copyright holder can tell youtube which countries to allow to see the video. So some people from some countries may not be able to see the video at all.
