In May, Vellum's James shared an ordeal that many people were able to relate to. Apple Music had deleted music files from his computer. It's an issue that many of us have faced over the years. At the time, Apple noted that it didn't actually know what was causing this. But it appears, it has finally figured out the issue and patched it. Jim Dalrymple, reporting for The Loop: One of the biggest complaints about Apple Music over the past year was that it wouldn't properly match songs subscribers had in their existing iTunes libraries. That problem is being fixed by Apple. Apple has been quietly rolling out iTunes Match audio fingerprint to all Apple Music subscribers. Previously Apple was using a less accurate metadata version of iTunes Match on Apple Music, which wouldn't always match the correct version of a particular song. We've all seen the stories of a live version of a song being replaced by a studio version, etc. Using iTunes Match with audio fingerprint, those problems should be a thing of the past. If you had songs that were matched incorrectly using the metadata version of iTunes Match, the new version will rematch to the correct song. However, it will not delete any downloaded copies of songs you have in your library. This is a very good thing -- we don't want songs auto-deleting from our libraries.
