Users can add all tracks to a "Collection" section of the app, rather than adding to a specific playlist. The features were announced by CEO Daniel Ek at a press conference, with Ek stating that a common user complaint about the service was that "Spotify is great when you know what music you want to listen to, but not when you don't", adding that "20,000" new songs got added to the service on a daily basis. "You're fighting with 20 million songs on Spotify", Ek
Slacker Slacker A slacker is a person who habitually avoids work or lacks work ethic. According to different sources, the term "slacker" dates back to about 1790 or 1898. It gained some recognition during the British Gezira Scheme in the early to mid 20th century, when Sudanese labourers protested their relative powerlessness by working lethargically, a form of protest known as "slacking". In the United States during World War I, the word "slacker" was commonly used to describe someone who was not participating in the war effort, especially someone who avoided military service, an equivalent of the later term "draft dodger".
