I havr three that I really enjoy, honestly most of them are sad because I love the way the voice is expressed in slow, sad songs rather then fast pace, jumpy songs. Anyways, my three favorites are Hello by Adele, Amnesia by 5SOS, and Dancing On My Own cover by Callum Scott.
"The King of Bedside Manor" by The Barenaked Ladies
"The House That Dripped Blood" by The Mountain Goats
"Maybe" by The Ink Spots
(I want to put something by Mark Germino, but I am torn between "Burning The Firehouse Down (With Firehose Extension)", "Let Freedom Ring [Volumes 4, 5, and 6], "Rex Bob Lowenstein", "Leroy and Bo's Totalitarian Showdown", and "Exalted Rose".)
