Queen got No. 1 in Oricon Chart(authoritative Japan chart). The last time they got No. 1 in Japan chart is 1976, as far as I know.
You can read it on official oricon chart: http://www.oricon.jp/index4.html
The first line means : "Oricon Chart Information 9th Feb. Queen got No. 1 27 years after they got it last time. Their No. 1 interval is the widest since the chart was born!"
You can get the detail as PDF format here: http://www.oricon.jp/chart_info/data/2004.2.9.pdf
I can't read it as my acrobat program doesn't support Japanese. :(
and I guess the album that got No. 1 on the chart is this new album by Toshiba EMI: http://www.toshiba-emi.co.jp/queen/disc/data/jewels.htm
As far as I know, the album is a kind of OST of a popular Japan drama, 'Pride'. The program rating of the drama is No. 1 now, and it was telecasted on Fuji TV, 4 times since January 2004. Its story is about popular writer and actor(or actress). The main theme is Born To Love You. And EVERY other theme with vocal is QUEEN!
