Actually none of the included site can find few of my albums...
however amazon.fr and amazon.ca got some of the albums i have (no clue why amazon.com does not have it)
is there a way to add a new search engine?
or a way to input a direct link to the webpage?
Have a look at /c/web-sources-scripts
and whether you find a ready-made src-script to meet your needs.
If not, you would have to write one of your own.
