As rumored earlier this month, Spotify is expanding its core free mobile streaming service, creating a tablet version of its app that offers the same features as the desktop version. So far, mobile users in the free, ad-supported tier could access a streaming radio service with the option of skipping a handful of tracks, a service that was launched in mid-2012. But putting up a chart of declining PC sales, Spotifys Daniel Ek said that it no longer made sense to distinguish between traditional computers and tablets. This was only one part of the news for Spotifys mobile business today.
