Songza was a free music streaming and recommendation service for Internet users in the United States and Canada. Stating that its playlists are made by music experts, the service would recommend its users on various playlists based on time of day and mood or activity. Songza offered playlists for activities such as waking up, working out, commuting, concentrating, unwinding, entertaining, and sleeping. Users would vote songs up or down, and the service will adapt to the user's personal music preferences. Users would find playlists not just based on artists, songs, or genres, but also based on themes, interests, and eras, such as "90s One-Hit Wonders", or "Music of Fashion Week".
