There are many songs that are appropriate to play at a funeral including "My Way" by Frank Sinatra, "Tears in Heaven" by Eric Clapton, "Angels" by Robbie Williams and "Ave Maria" by Scubert. Determining what kind of emotional mood is desired will indicate which songs are selected for the ceremony.
"Over the Rainbow" by Eva Cassidy, the classic song of hope from "The Wizard of Oz" film, is also a perennial favorite for a poignant farewell. For a more uplifting tone there is "Spirit in the Sky" by Norman Greenbaum, "Come Away With Me" by Norah Jones or the island-style version of "Somewhere Over the Rainbow" by Israel Kamakawiwo’Ole.
If a humorous air is appropriate for the funeral, then a few titles to think over are "Keg on My Coffin" by the Push Stars, "Roll Me Up and Smoke Me When I Die" by Willie Nelson, "Ring of Fire" by Johnny Cash and "Dropkick Me Jesus" by Bobby Bare. Additional popular farewell songs include Sarah Brightman and Andrea Bocelli's "Time to Say Goodbye," Nat King Cole's "Unforgettable," The Beatles' "In My Life," Bette Midler's "Wind Beneath My Wings," Cyndi Lauper's "Time After Time" and "Wish You Were Here" by Pink Floyd.
