Thanks very much for the replies. Here are my comments...
Play.com fails on item 2 on my list. You select sacd and you only get a list of 5 or so discs. You've then got to top selling to see more...but what if the music I like isn't top selling where do I find it?
Amazon fails on item 4. Also repeats titles over and over again as you page down
dvdpacific are good. Once you realise there is a little hyperlink thing in point6 font on the top right of the music page. They eventually fail on item 4 as well.
dvd4music seem to be the best. Although it would be nice to pick the genre. paging through all the classical music is a bit boring.
dvdboxoffice seem to have improved their site. You can actually filter by format and genre. So for instance you can select dvd-a, sacd and pop. ALthough they fail on item 4.
I didn't think I was asking for much. Maybe I'm getting fussy in my old age. I have to combine the info from two sites to decide whether to buy a disc
