My country, Chile, has a very long tradition of political songs. Quilapayun wrote many a song to support the Election of President Salvador Allende.
Just heard this song today. It's not a pro- song, but an anti- song. At least, someone took the trouble to write into lyrics, and compose a piece of music to support their feelings. I like it. Their site is here: http://www.onsfoudkilao.com/
And I'm open to listen to contributions from both sides.
