Would love to have a look. It just hangs on "loading". Also, the authentication window opens in a non-viewable format (entry box is huge, cannot resize or re-position to fix the problem). I resolved that by copying the link and then opening a new full-size window and going from there.
However, as mentioned, it then hangs on "loading".
EDIT:
I resolved this by using a web app creation tool (I prefer "Unite 2", but there are multiple options, including DIY with Chrome). Although it apparently hung up again, when I dismissed that page, the initial page had loaded with my Artists, Albums, Songs and Playlists.
The sound quality is noticeably better than the first attempt of this kind which I tried (playapplemusic? - I am uncertain of the name). There are bugs, but this is promising. Thanks to the developers.
