A national anthem is a generally patriotic musical composition that evokes and eulogizes the history, traditions and struggles of its people, recognized either by a country's government as the official national song, or by convention through use by the people.
AllNationalAnthems.com is a website dedicated to collect all Anthems in the world, currently collected 184 countries (yup i count em :P). The good thing about this is the Anthem comes in video format :) So you can see some footage or overview of the country while you hear the Anthem (which probably you don't understand most of them :P)
There are 2 ways you can choose a country. First is using the Yahoo!Maps above, which is easy to navigate. Just scroll around click here and there.
The other is, you go straight away to the bottom of the page, search for the specific country, and click the link ;) If you have trouble seeing those link, then if you're Firefox users or IE7+ users, just press Ctrl + on your keyboard ;)
Inside you'll then find a brief summary of the country, followed by a video of the anthem :) Nice and simple !
Scroll down a little, you'll get to know the weather, the map, and basic information such as population etc.
The data so far is quite up-to-date. The population estimate is from 2007. Which is good ^^
So far AllNationalAnthems.com have given a pretty solid value, the Anthem and some basic summary and information ;)
The only thing that needs to be add is a home link/button. Once you go in to specific country, either you browse through another country using the Yahoo!Maps, or change the url address, and pick the link again from the beginning :P
Have a try and have a nice weekend ^^
