Why Your Downloaded Music Disappeared on Your New Phone
Your playlists came back. Your downloads did not. That is not a bug in your music app — iOS deliberately leaves offline files out of every backup. Here is why, how to tell 'gone' from 'still loading', and how to rebuild in minutes instead of hours.
The short answer
You set up the new iPhone, everything came back — contacts, photos, apps, playlists, even your place in a podcast — and then you got on a plane and found every downloaded song was gone.
Nothing is broken and you did not do the restore wrong. iOS deliberately excludes offline downloads from backups, in every music app, by design.
Apple asks developers to flag anything that can be fetched again from the internet as excluded from backup. Downloaded songs, Netflix episodes, podcast episodes and offline maps all qualify. So the backup carries the *record* that you downloaded a song, and not the audio file itself.
Your library is safe. What you lost is a cache — a large, slow-to-rebuild cache, but a cache.
Why Apple does it this way
It looks like a bug, and there is a real reason for it.
iCloud backups are size-limited and slow. If every offline download went into the backup, a 40 GB music library would make your backup 40 GB larger, take hours over home Wi-Fi, and push you into a paid iCloud tier to store bytes that are already sitting on a server somewhere.
So the rule is: if it can be downloaded again, it does not go in the backup. The alternative is worse for almost everybody.
The same rule applies whether you restore from iCloud or do the direct phone-to-phone transfer during setup, and it applies to a same-phone restore too. If you have ever wiped and restored an iPhone and found your Spotify or Apple Music downloads missing afterwards, this is why.

Is it actually gone, or just not loaded yet?
Worth checking before you rebuild anything, because a new phone is busy for a day or two.
Signs it is genuinely gone: the download indicator is missing next to songs, and playback fails with no signal. In Trending Music the downloaded badge comes from a real check of the files on disk — not a saved flag — so if a song shows as not downloaded, the file really is not there. That is deliberate: a badge that lies is worse than no badge.
Signs it is still settling: everything works on Wi-Fi, artwork is missing or grey, and the library looks thinner than you remember. Give the phone a night on Wi-Fi and power before you conclude anything. Photos and app data keep syncing long after setup says it has finished.
Signs it is an account problem instead: your playlists are missing too, not just the audio. Downloads vanishing while the library stays intact is the backup-exclusion story above. Library *and* downloads vanishing usually means you are signed into a different account than you think — check which account is signed in before you re-download anything.
Getting them back, in the fastest order
Rebuilding is mostly waiting, so the trick is to be deliberate about what you wait for.
Do it on Wi-Fi, on power, with the app open. Large downloads on cellular are slow, expensive, and on some plans throttled. iOS is also much more willing to keep a download running while the device is charging.
Re-download in priority order, not all at once. Start with the things you will actually need offline in the next few days — the commute playlist, the album you are currently obsessed with, whatever you want on a flight. Queueing the entire library at once means the one playlist you need tomorrow finishes last.
Be honest about what you actually used. This is the one genuine upside of losing the cache. Most people re-download three or four playlists and discover they never missed the other forty. A new phone is the cheapest chance you will get to not rebuild the pile.
How to avoid the scramble next time
You cannot make iOS put downloads in the backup. You can stop being surprised by it.
Download before you need to be offline, not before you migrate. Any downloading you do the night before switching phones is wasted work — those files are the ones that will not survive.
Keep the list small enough to rebuild. A focused set of offline playlists is fifteen minutes on hotel Wi-Fi. An entire library is an afternoon.
Offloading an app is not the same as deleting it. iOS "Offload Unused Apps" removes the app binary and keeps its data; deleting the app removes everything, downloads included. If you are short on space and want to keep your offline music, offload rather than delete.
Check before the flight, not at the gate. The only reliable test is airplane mode: turn it on, open the app, and play something. If it plays, it is genuinely on the device.
This is not specific to one app
It is worth saying plainly, because people often switch apps over this and land in the same place.
Spotify, Apple Music, YouTube Music, Amazon Music and Trending Music all lose downloads on a new device, for the same reason. Any app that tells you otherwise is either re-downloading in the background without telling you, or it is storing audio somewhere Apple would rather it did not.
Where the apps genuinely differ is what happens around the loss: whether your library and playlists come back intact, how quickly you can queue a re-download, and whether the app is honest with you about what is actually on the device. Those are fair things to compare. "Does it survive a phone migration" is not — none of them do.
Trending Music keeps your library on your account rather than on the handset, so signing in on the new phone brings back every playlist and favourite. The audio still has to come down again, same as everywhere else.
