Plugin for Youtube video that doesn't open.

When I do a post in my WP blog, I like to put in a Youtube video so the reader can listen to the music related to what I writing about. I size the embed so that just the play button is exposed (it’s like 50 X 25). So the reader hits the play button to read and listen. However, I don’t want the Youtube video page to open.

I use to be able to do that but I’ve forgotten how and can’t figure it out. It has something to do with the plugin, that allows the music to be played but the Youtube video doesn’t open over top of my blog.

Can someone help?
