Apple Music Matches Files with Metadata Only, not Acoustic Fingerprinting ➝

Kirk McElhearn:

Apple Music, however, works differently. It does not use the more onerous (in time and processing power) acoustic fingerprinting technique, but simply uses the tags your files contains. And it can lead to errors. Here’s an example of how this can be a bit surprising. […]

Since Apple Music matches only using tags, it can’t tell the difference between, say, a studio recording and a live version of a song. Or an explicit version and a clean version. This explains why, for example, Macworld editor Susie Ochs found that a live Phish album was replaced by studio versions of the same tracks.

This explains a lot — like how Apple Music can’t seem to differentiate between acoustic and non-acoustic versions of songs on different albums if the tracks have the same name. But if Apple was able to use acoustic fingerprinting with iTunes Match, why not with Apple Music?

Update: Turns out, this might not be reproducible.

The Real Difference Between iTunes Match and iCloud Music Library ➝

Kirk McElhearn:

When you match and download files from iCloud Music Library (without having an iTunes Match subscription), however, you get files with DRM; the same kind of files you get when you download files from Apple Music for offline listening. (These files should have DRM, so you can’t just download and keep all the music you want for $10 a month.) But if you’re using Apple Music, and not iTunes Match, Apple doesn’t make a distinction between which files were originally yours, and which you downloaded for offline listening from Apple Music.

If you plan on making use of iCloud Music Library, be sure to keep copies of your original files. Otherwise, you’ll be stuck paying for Apple Music indefinitely or risk losing your music library all together.

Apple Releases iTunes Match ➝

It’s two weeks late, but its’ finally here. I haven’t signed up for it yet, but think I’ll be doing so before too long. I have a lot of music that I ripped from CDs years ago. It would be nice to upgrade that music to a higher bit rate without having to dig the discs out of the closet and re-rip the whole lot.
