This song seems to be quite relevant today. It samples Martin Luther King Jr.’s “I Have a Dream” speech, which relates to the lyrics of this song about racism. The song was made for the movie “Freedom Writers” and was produced by will.i.am, who also sings in the chorus.
Note: the song is not available on Spotify or Apple Music (at least in my region), so I only provided a link to YouTube. I recommend watching the music video anyway.
