had a quick try, definite improvement, smoother scrolling, art loads quicker, less lag. good all round really. couple of things i noticed (dont know if they're new or not though i'm hardly using scientific protocol to test!)

music doesn't work on silent profile
on general profile if a text is reveived music cuts out and doesn't restart itself.
some previously found artwork has disappeared
one album now has coverart of *this picture has been moved or deleted* (sure this cant be helped due to the nature of the art retrieval, but perhaps a case for a "search again" option)

thanks again all at instinctiv for your hard work.
