I found this song, Samba da Utopia, while wandering through YouTube. The composer's video is here, but there are many, many other videos by cover singers--like this one, which I almost like better. The words and tune are simple and the message is a good one (aside from the minor detail that I don't believe in utopias)--I really like it!

PS, I don't actually know what makes a samba a samba--I should find out.
