Thats apparently a lesson Beats is learning the hard way. Billboard reports that Beats Music is off to a slow start and has put together disappointing subscription numbers in its first 100 days since launch. But industry insiders tell BIllboard that Beats Music isnt yet taking off like anyone had hoped. The company was late to a market with established players like Spotify, Rdio, and Google Play Music All Access; But Billboard also notes that music labels remain committed to Beats Music for the long term. And investors appear eager to chip in, too.
