In response to the last 2 music videos someonewhodied posted: That violinist needs more skill. And better recording.
And now onto the actual rating. I can't count the number of times I've heard Greensleeves on the piano, and as a result of that I've come to hate it. And again, youtube's crappy music quality brings it down. The woman performing is definitely good, though. And I do enjoy the harp. It's a wonderful instrument. Such a shame there's so little harp music to be found.
Really hard to rate this, but I'll give it a 8/10 for now.
