It's no secret that Apple plans on revealing a new streaming music service -- thanks to its Beats Music acquisition -- some time this year, supposedly at its annual developer conference in June. What has so far been a secret, however, is whether or not that service will be free or paid. While it's been widely reported that Apple plans on charging $8 a month for a subscription, it now appears that the folks in Cupertino could be planning on integrating a free option or two as well. According to ReCode's industry sources, those options include a free trial period of one to three months, a SoundCloud-type service where artists could upload free tunes for non-subscribers, and a new version of iTunes Radio that would feature human-curated playlists similar to, of course, Beats Music.
