It's been 50 years since Martin Luther King delivered his I Have a Dream speech during a civil rights rally at the Lincoln Memorial in Washington.

The impact of the speech reached beyond the civil rights movement, leaving a lasting impression on popular culture. Music was particularly influenced, with the immortal words making their way into a number of songs over the years. So, without further ado, here's a playlist from Spotify featuring 10 songs that include the word "dream".
