Almost all songs on this kind (a soloist with a guitar) have a certain heartwarming appeal, ever since Nicole started it in 1982.
Iceland's 2011 entry was "Coming Home" by a band called Sjonni's Friends, which only formed because the writer of the song, Sjonni Brink, died days before he was meant to perform it in the Icelandic national selection. Sjonni's musician friends, believing the song should stay in the competition, formed a tribute band and took the song all the way to Eurovision (it finished 20th).
Malta's entry for 2013 was Gianluca Bezzina, a Hospital Hottie with an exceptionally sweet song called "Tomorrow", detailing the love story between IT Guy Jeremy and his Manic Pixie Dream Girl. The song (reminiscnet of Jason Mraz's "I'm Yours) placed 8th in the finals and was Malta's most commercially successful.
