Ive found an inconsistency in the returned form of isrcs when using JSON search API.
I am only finding the isrcs in the for of a kvp when "Search" requests return, as in contrast to Browse/Lookup requests where only an array of isrc values are returned.

In each returned recording you will find each isrc in the kvp form:
but as mentioned all other Browse/Loolup request return something like:
and from what im told this is inconsistent with the what the xml API defines.
(I havent used the xml API) thus im assuming its a bug rather than an improvement
