It would be nice to add URL matching for the discography page relationship type. The ones here are the most common Japanese label pages which have a consistent URL scheme in our database and can therefore be easily matched (this is obviously not everything, but we can create new tickets for other sites). The regexes are the strictest ones I could do to match the URLs, but we probably want to make them match https and www/no-www too.

Example URL: http://www.universal-music.co.jp/sweety/products/umca-59007/
Regex: ^http://www.universal-music.co.jp/([a-z0-9-]+/)?[a-z0-9-]+/products/[a-z]

{4}-[0-9]{5}/$

Example URL: http://www.lantis.jp/release-item2.php?id=326c88aa1cd230f96ef350e380a23078
Regex: ^http://www.lantis.jp/release-item2.php?id=[0-9a-f]{32}$

Example URL: http://www.jvcmusic.co.jp/-/Discography/A007461/VIDL-10827.html
Regex: ^http//www.jvcmusic.co.jp/[a-z-]/Discography/[A0-9-]/[A-Z]{4}

-[0-9].html$/

Example URL: http://wmg.jp/artist/ayaka/WPCL000010415.html
Regex: ^http://wmg.jp/artist/[A-Za-z0-9]+/[A-Z]

{4}[0-9]{9}.html$

Example URL: http://avexnet.jp/id/supeg/discography/product/CTCR-11051.html
