On July 7 1992, Madonna contributed This Used To Be My Playground to the Special Olympics benefit CD, Barcelona Gold.
This Used To Be My Playground was the theme song to the hit film A League of Their Own, but it was not included on the film soundtrack. The soundtrack for the film was released by Columbia Records, while Barcelona Gold was released by Warner Bros., possibly the reason why Madonna’s hit single appeared on the benefit CD instead of the soundtrack.

The feeling and emotion of Playground is universal! I am touched and moved by Madonna! Madonna is Love!
