Hail there
I just tested a few things, at least all i could do, everything sounds fine to me.
One thing i noticied but i don't know if it's on purpose or not at the moment, but the redirection link for collection while you browse 1 album does not work.
( the "Contained in xx collections" ), it's used to browse who got the title in their collection but it does not work for now.
It's kinda weird to post the tracklist after you posted the album, i was afraid when i saw the empty tracklist information, i realised i could edit it after that..
Maybe you could modify the forms to add tracklists and covers at the same time? Page 1 is catalog, Page 2 is informations, Page 3 tracklist ?
Other than that, it looks awesome and it's just a matter a tweaking now..
I wish i could add scans since i got Gigs for them
