User blog:JoshuaJSlone/Big source for old song/release information

Miyoshi Chinatsu being a pretty minor artist who was most relevant at the turn of the century, there's not a great deal of information out there about her singles. But while trying to search for some more, I stumbled across something of a motherlode of Hello! Project-related information in Japanese, at least for prior to 2006.

http://tsunku.nomaki.jp only has three functional links, two to XLS files (for use in various spreadsheet programs) and one HTML.

The Release XLS lists singles/albums along with artist, release dates, and all tracks. Without checking all 1900+ rows, I'm pretty sure most of this is already represented here.

The Artist XLS gives more detail. It splits things up by artist, but then additionally lists catalog codes for each release, and Arrange/Lyrics/Music credits for each song.

The Artist HTML only has Morning Musume information, but most of the page contains all the little information contained in liner notes, like who played bass or who was in the chorus.

Of course the big caveat is that this is all just sitting there unsourced--but as long as what we know from elsewhere matches up I'm inclined to believe the rest. There's so much information here I've only checked out a small portion, though.
