Casey Kasem In Hospice Care -- Family Playing 'Top 40'

Casey Kasem is living out the final days of his life by listening to the best days ... his family has been playing old recordings of his "American Top 40" show while he lay dying in hospice.

Casey is currently in a Washington hospice with his family by his side ... including his daughters, son, and brother. Family sources tell us ... the family is playing old broadcasts of Kasem's legendary radio show ... the crowning achievement of his career.

Now that the family has stopped giving him medication, food, and water ... they're just trying to make him as comfortable as possible ... and they believe the broadcasts will give him great enjoyment.
