Apple Music includes an option with its sharing menu to open a song or album in the iTunes Store if you wish to buy it, but there isn’t currently a way to do this in reverse. I still like to browse the iTunes Store, but having to switch between apps and perform a search see if an album is available on Apple Music is a bit of a chore.
Starting with iOS 8.4, iTunes Store links now open in the Music app, rather than the iTunes Store. Using a Workflow action extension, it’s simply a case of getting the iTunes Store link to a particular album and then immediately opening it. When the URL is opened, the default behaviour takes over and the album is then opened in the Music app. Now, if I stumble across an album in the iTunes Store that I want to stream with Apple Music, I just open the share sheet, tap “Run workflow” and then select “Open in Apple Music”.
Despite the new behaviour for iTunes Store links, it’s still possible to specify whether a link opens within the Music app or the iTunes Store by adding either
&app=itunes to the end of an iTunes Store URL. I’ve included the former in the workflow simply to ensure links open in the Music app.
