It’s been a busy week for US streaming music service Lala, following news that it’s working with Google on a new music search service, and with Facebook on music gifting. Now Wired’s Epicenter blog is reporting that Lala is also working on its own iPhone application, which will tie in with its website. That means users who’ve paid 10 cents for unlimited streaming rights to a song will be able to stream it on iPhone too for no extra cost. The app will also provide access to users’ own libraries of music. It’s expected to be available by the end of the year – IF Apple approves it.
