Hypebot says the long-expected service might cost $20 a month, and allow users to store all their music and other content in "the cloud", so it would be available to the user on any mobile device. Hypebot says the much-rumored debut from Apple “places pressure on Slacker to get their on-demand service to market, and for Spotify to finalize their U.S. deals” with record labels. Spotify is popular in the UK and Europe, but is still lining up its supply deals for the U.S. market. Historically, Americans have been slow to adopt the cloud-based approach, preferring to store music on their own devices.
