Getting Top 200 songs for a certain Genre

All,

I found the following link about genre mapping within iTunes:

http://www.apple.com/itunes/affiliates/resources/documentation/genre-mapping.htm l

If I look for country for example I know I can use this url:

http://itunes.apple.com/us/rss/topsongs/genre=6/json

However this only returns the top 10 songs at the moment. If I search for Country in iTunes it will display these top 10 on the right hand side and that's fine but then you can click on see all and it will show you the top 200 songs. How can I obtain those songs using this method? I'm ok with also using the Web Search API and actually prefer to use this method but not sure how to use it to search for genres.

Any help you can provide would be greatly appreciated.

Thanks!
