Garth Brooks: 'We Shall Be Free' -- http://www.youtube.com/watch?v=Gg9Me90bvtA
When I heard this song and saw this video as a young child (the song came out in the early 90s, and I'd heard it by 3rd or 4th grade)... I was just electrified. I hadn't heard a song sung about human rights and freedoms before. Especially the lines "when we're free to love anyone we choose, when this world's big enough for all different views, when we're all free to worship from our own kind of pews... we shall we free". I just thought "oh, wow!"
Brooks wrote the song in reaction to the 1992 riots in LA. So I know the video is dated by about 20 years, and yes, it does reference religion... but I still LOVE it. Because most importantly, it refers to freedom, to tolerance and acceptance, to getting rid of prejudices and hatred. That spoke to me as a kid, and it still speaks to me now.
