Staving Off Bittorrent

One thing the Internet really needs is a site that matches record labels to MP3 vendors. You could then fill in artist and album-specific links, but basically I really want to know something like, Where can I buy the new Six Organs of Admittance record online?

Now, I know they're on Drag City, which means eMusic doesn't have them and apparently neither do Insound and Other Music. However Amazon is carrying it for $17.98 and iTunes has it for $15.99. But this is all at least label-specific information, if not album specific. For example, some labels only provide part of their catalog to certain stores, and I know eMusic sometimes receives albums long after their original release date, if ever.

This should pretty much be Google Shopping* with an awareness of international restrictions (Bleep won't let Americans buy a lot of rock music, but most of their electronic stuff is okay) and store preferences, since if thirty sources are selling a record for $9.99, I'd rather not have to page through a bunch of junk to get to eMusic or Other Music, which are my preferences for indie rock type stuff. And it would need to include iTunes and any other sources that aren't directly available through a browser.

*Yes, I tried doing a relevant search on the actual Google Shopping, and it was completely useless.
