Google's Intriguing Access to iTunes Music Library

Hello! Today, I want to discuss something intriguing that caught my attention a couple of months ago and has been on my mind ever since. It appears that Google has found a way to scrape data from an iTunes music library on the same device through one of their apps. However, I'm uncertain which app is responsible, and it doesn't seem to involve any information sharing or consensual data sharing with Google.

The Mystery of Unrelated Music Recommendations

I have a specific set of music, primarily tracks I copied into my iTunes music library years ago, which are now part of my Apple Music library. These tracks have never left the app, and I don't search for these artists or songs on YouTube. Interestingly, this niche music from my library began appearing in YouTube notifications and recommendations around November or December, seemingly out of nowhere.

Unexpected YouTube Music Suggestions

YouTube started suggesting, "Hey, you don't listen to music on YouTube. Why don't you try YouTube Music? We already have all of your music from your library. You could switch right now and start listening." This was surprising because my music was siloed in iTunes and Apple Music. I'm unaware of how Google could access it without some OAuth mechanism.

Potential Data Access Methods

In iOS app development, there's a mechanism to add a "Sign in with Apple Music" button, allowing third-party apps to access data. However, it seems Google has found a way to scrape song names and artist names from the entire iTunes music library, possibly through one of their installed apps on my device. This data appears to be used to promote YouTube Music, a competitor app.

Apple's Potential Concerns

It's puzzling because one would assume Apple would go to great lengths to prevent a competitor app from scraping this data. Presumably, the only use for this data is to advertise within Google apps, encouraging users to migrate from Apple Music to YouTube Music. It's surprising that Google has managed to achieve this, despite Apple's likely efforts to prevent it.

Distinguishing from Common Misconceptions

Before jumping to conclusions, I've thought about this extensively. This isn't like those instances where people Google something and then see related ads elsewhere, not understanding how tracking works. I'm aware that phones aren't spying on us in that manner. While this situation might sound similar, I've considered it for months and can't think of any way Google could access this information except through an app installed on the same device.

Possible Methods and Speculations

Perhaps it's easier on macOS, and maybe Google used the Chrome binary to read my iTunes music library, which would be even more surprising. Whatever method they employed to obtain this data is likely interesting, and I imagine there are some Apple developers sending angry emails to Google about not adhering to developer terms.

In conclusion, I find this situation fascinating and worth pondering. How Google managed to access this data remains a mystery, but it certainly raises questions about data privacy and app permissions.
