What song was playing in harry potter,order of the pheonix(movie), before shamus started to argue with harry?

So i was watching the Movie Harry Potter and then i hear a song i've heard before but i couldn't put my finger on it. The music was played right before Shamus and harry start to argue about the Daily Prophet. it was during the time when harry walks into the Griffindor corridor for that first time and every one is looking at him. PLEASE HELP ME!!
