I am not really too talented musically, though I do want to say that I have learned very much using the WI and GPO libraries and for that I am thankful. The selection is quite good, especially when compared with other world libraries. I believe the price of $150 is something of an honest price - something rare in a world where people get so greedy, imo. I really like the amount ethnicity this library offers.
In short I like this library - very, very much.
Just wanted to mention those things and hope the WI library continues to grow.
