It looks like the product pages are dynamically created based on the product id in the URL (e.g. 2776 from your product page example). This product page could be updated to dynamically produce a different title based on this same information.
For example:
$product = getProductByProductID(2776);
$artist = getArtistByArtistID($product->artistID);
<title><?php echo "$product->name by $artist->name"; ?></title>
?>
Mind you, this is PHP code and you are using RESTful URLs so your site is likely written in Ruby - though I'm just guessing here.
For Ruby, this is essentially pseudo-code as I am not a Ruby developer by day (though I did stay in a Holiday Inn Express last night), but I believe you are looking to do something like this in your controller:
def product_page
@product = Product.find(params[:id])
@artist = Artist.find(@product.artistid)
@page_title = "<%[email protected]%> by <%[email protected]%>"
end
Then in your page template you can use:
<title><%= @page_title %></title>
Hope this helps and sorry if it is too technical/cryptic; but your developers should be able to do something like this pretty easily. It appears to already be underway to produce the rest of the page content. Now they just need to use it to populate the page title (and maybe the meta description - use part of the product description).
