Lisa Nilsson (born August 13, 1970 in Tyresö) is a Swedish singer. She was discovered by the producer William (Billy) Butt and she is perhaps best known in Sweden for her 1992 hit, "Himlen runt hörnet", written by Mauro Scocco and Johan Ekelund. It was released in English in 1995, titled "Ticket to Heaven". She has released four subsequent albums, "Till Morelia" in 1995, "Viva" in 2000, "Små rum" in 2002 and "Hotel Vermont 609" in 2006, all in Swedish. A greatest hits compilation, "Samlade sånger" followed in 2003 and contained two new songs. Prior to "Himlen runt hörnet" she had released two English language albums, "Lean On Love" in 1989 and "Indestructible" in 1991, both released by William Butt.
