I had a cousin who died unexpectedly in 1984 at the age of 16. One of the songs sung at her funeral was Over The Rainbow, because she loved rainbows.
I really wanted to have that played at my father's funeral, since he liked the song "Over the Rainbow". But, since he was Catholic, the priest said a hymn had to be played. I asked that they play "On Eagle's Wings" and something else. I didn't even recognize what was played.
