The imminent launch of Beats Music is causing Spotify and Pandora to do some back peddling. Pandora’s personalized music streams, that will incorporate listener tendencies into recommendation engines, and Spotify’s International removal of free listening caps both come within a week of Beats’ launch. Beats Music claims to do both of these things – algorithmic artist discovery and custom streaming stations with unlimited play time, anywhere – which before this week Spotify and Pandora didn’t sponsor. Although Pandora is still the number one streaming service in the U.S. market, but Spotify is making rapid gains in an attempt to solidify its position in advance of the Beats Music launch. We’ll have to wait and and see how Beats Music does – or doesn’t – shake up the already competitive music streaming market.
