Spotify wants to take on Netflix (NFLX +0.5%), sources tell BI. The popular music subscription service reportedly plans to launch an on-demand video service that will invest in original content. As both Netflix and Amazon can vouch, building a quality service won't come cheap. Might Spotify try to go after foreign markets Netflix hasn't yet expanded to? Update: A source tells CNET Spotify is "in the early stages of exploring a possible video service."
