I like the Uruguay anthem. Not the lyrics, they are a bit dark (the anthem is even named "Orientals, the Fatherland or the grave", but at least it doesn't sing about blood washing away polluted footsteps like the american anthem), but the music and vocals are great. Way more epic sounding than most countries.
The anthem of Singapore has a good positive message, no mention of war, religion, aggression, etc.
Let us, the people of Singapore Together march towards happiness. Our noble aspiration is to make a success of Singapore. Let us unite With a great new spirit Let us proclaim Onward Singapore! Onward Singapore
Now that's an attitude I really respect. (The music isn't as good as the Uruguay one though)
