> **Notes**
>
> - While iTunes is still available, it has been discontinued. Apple has split iTunes functionality into several apps: Apple Music, Apple TV and Apple Devices / Finder integration for syncing. MacOS also has the Podcasts and Books apps; for Windows, iTunes is still necessary for managing and syncing podcasts and audiobooks.
> 
> - iTunes has more functionality suited for users with local collections like converting to MP3 and other legacy features; Apple Music and TV is better suited to users with subscriptions to stream media which doesn't allow or does not require metadata to be edited. Apple Devices is then required to sync these two newer libraries; iTunes is an all-in-one solution.
> 
> - Get Info in iTunes is renamed to Properties in Apple Music/Apple TV.
> 
> - Apple is strongly centred around MP4 and M4A which can contain other codecs like ALAC. Other formats based on MP4 like M4V/M4B can be read by Apple software and Mp3tag, M4R/M4P cannot be read by Mp3tag due to DRM protection.
> 
> - MP4 is recognised as a song if there is no video track, only audio; M4A is just the same but as an "official" way of formatting an "Audio MP4".
> 
> - Multiple values using `\\` as a delimiter has always been broken, i.e. for `ARTIST` you'll have to choose either `artist1/artist2`, `artist1; artist2` or `artist1, artist2 and artist3` to denote multiple artists.
> 
> - Play counts, skip counts, ratings, love (❤) and favourite (⭐) can only be set in iTunes and are saved to its database, not via any tags.
> 
> - WAV can be imported and is playable but reads no metadata from the file. Limited metadata can be input via iTunes into its own database rather than into the file.
> 
> - The only way to enable gapless playback in Apple Music is using M4A's with the correct `ITUNSMPB` tag, `ITUNESGAPLESS` is optional. Using M4A without the tag has a short click in between tracks. iTunes is _slightly_ better but still not reliable.
> 
> - MP3 gapless playback is broken in Apple Music even with appropriate tags: consider using M4A's or an [alternative player](https://community.mp3tag.de/t/ios-media-players/58847).
> 
> - ReplayGain is not used, instead `ITUNNORM` is used for M4A/MP4. _Investigate $rg2sc()_
> 
> - iTunes Match may have issues with metadata, some can be altered once matched but some cannot be fetched like animated artwork.
> 
> - Artist pages/profile pictures are _very_ buggy and can be retrieved by the synced device during sync, sometimes are retrieved by iTunes, never by Apple Music, always when a file has `ITUNESARTISTID`, sometimes automatically by `ALBUMARTIST`/`ARTIST` where available. Once assigned, the only definitive way to update it is by deleting the app, re-installing and re-syncing.
> 
> - Apple Music / Apple TV saves videos as fragmented files to stream together; iTunes saves videos as M4V files.

> **Troubleshooting**
>
> - If metadata doesn't change immediately in iTunes / Apple Music / Apple TV:
> 
> - If metadata doesn't change on a synced mobile device:
> 
> - If any issues occur where metadata can't be updated or removed on a synced mobile device whatsoever:
> 
> - If you accidentally set `ITUNESMEDIATYPE` to Podcast on an M4A and the file becomes hidden:
