Couldn't agree more with this post from MacStories. The original story they are covering is this post from the app developer Steamclock about limitations that third party apps have when accessing iTunes tracks stored in the cloud.
From Steamclock's blog post:
According to our latest stats, 17% of Party Monster users have been unable to play a song in their iTunes library, and 22% of WeddingDJ users have tried to cue a playlist that has so many unplayable tracks that we need to display a warning. While it’s a miracle that we’ve been able to maintain a 4 star rating through all of this, it’s not going to last if we stay the course.
Given all of this, we have a couple options. We could double down and go pro, catering to serious DJs who can load DRM-free music into our sandbox. Pro DJs who use our apps often have a large licensed library of songs, and won’t rely on iTunes Match or Apple Music.
Alternatively, we could steer towards the mass market, drop crossfading support, and regain full iTunes compatibility. We could also put in the work to add support for Spotify or other competing streaming services, and focus our apps less on playback features and more on having a great UI for queueing.
I am glad this problem is getting some publicity. I have been frustrated with the fact that iTunes tracks can't stream from third party apps for years.
