For the most part, everything was spot on. Didn't notice any wrong notes, no early or late starts, but whoever was playing the symbols during the Weasley Stomp did come in at the wrong times, and there were times when they were either going too fast like during Obliviate and Lord Voldemort, and moments were they were going too slow like in Nimbus 2000, Quidditch, Fawx The Phoenix, Elder Wand and the end of Leaving Hogwarts. Overall, I'd give them a seven out of ten.
