The fastest way: use iCloud Music Library

If you have an Apple Music subscription or iTunes Match, turn on iCloud Music Library in your iPhone settings and your iTunes songs will appear in the Music app automatically. Go to Settings > Music > toggle on "Sync Library" (on newer iPhones) or "iCloud Music Library" (on older ones). Your computer's iTunes library syncs to Apple's servers, and your phone pulls from there.

This method works even if your songs aren't DRM-free. Apple scans your library, matches songs to its catalog when possible, and makes them available on your phone within hours. You don't need a cable, and songs stay synced across all your devices.

The catch: you need an active subscription. If your subscription lapses, you lose access to songs that weren't originally purchased from iTunes. Songs you bought from iTunes stay yours, but matched songs disappear.

Key Takeaways

  • iCloud Music Library is the easiest route if you have Apple Music or iTunes Match — songs sync automatically without a cable.
  • Wired sync through a computer works for any song and doesn't require a subscription, but you have to plug in your phone.
  • DRM-protected songs (older iTunes purchases) can only move to your iPhone through iCloud Music Library or by removing the protection first.
  • If you use multiple computers, iCloud Music Library keeps everything in one place; wired sync only pulls from whichever computer you connect to.

Wired sync: connecting your iPhone to a computer

Plug your iPhone into a Mac or Windows PC with a USB cable. Open iTunes (on Windows or older Macs) or the Finder (on newer Macs). Your phone appears in the sidebar or window. Click it, then click the Music tab.

Check "Sync Music" and choose "Selected playlists, artists, albums, and genres" or "Entire music library." If you pick selected items, check the boxes next to the playlists or artists you want. Click Apply, then Sync. iTunes copies the songs to your phone.

This method works with any song file your computer can play — purchased iTunes songs, songs you ripped from CDs, or files you downloaded elsewhere. It doesn't require a subscription. The downside is that you have to physically connect your phone each time, and syncing only pulls from the computer you're connected to.

Understanding DRM and why some songs won't transfer

DRM (Digital Rights Management) is copy protection on older iTunes purchases. Songs bought before 2009 often have it; newer purchases and iTunes Match songs don't. DRM-protected songs can't be moved to your phone through wired sync — they'll simply be skipped during the transfer.

Your options: use iCloud Music Library (which bypasses DRM), or remove the protection first. To remove DRM, you can burn the song to a CD in iTunes, then re-import it into iTunes as an unprotected file. It's tedious for a large library, but it works. Alternatively, some third-party tools remove DRM, though this sits in a legal gray area depending on your location.

If you bought the song from iTunes, you own it — Apple just restricted how you could move it. iCloud Music Library was designed partly to solve this problem.

Syncing playlists and keeping music organized

When you sync through iTunes, your playlists come along. Create or edit playlists in iTunes on your computer, then sync your phone. The playlists appear in the Music app on your iPhone in the same order.

If you use iCloud Music Library, playlists sync automatically across devices — create a playlist on your phone and it shows up in iTunes on your computer. This is one reason iCloud Music Library is easier for people who manage music from multiple devices.

One limitation of wired sync: if you add songs to your iPhone through the Music app (by downloading them from Apple Music, for example), those songs won't sync back to iTunes on your computer. The sync is one-way, from computer to phone.

What to do if your iPhone storage is full

iCloud Music Library doesn't store full song files on your phone — it streams them or downloads them on demand. If storage is tight, this is the better choice. You can also download specific songs for offline listening without syncing your whole library.

With wired sync, every song you sync takes up storage space. If your library is larger than your phone's storage, you have to choose which playlists or artists to sync. You can also set iTunes to "Optimize storage" during sync, which automatically removes songs you haven't played recently to free up space.

Troubleshooting common sync problems

If songs aren't appearing after sync, check that your iPhone is set to sync music at all. Go to Settings > General > iPhone Storage and look for the Music app — if it shows 0 bytes, nothing is synced. Also verify that you're syncing the right playlists or artists; if you selected "Selected playlists" but didn't check any boxes, nothing will sync.

For iCloud Music Library, make sure "Sync Library" is on in Settings > Music on both your phone and your computer. If songs still don't appear, sign out of iCloud on your phone (Settings > [Your Name] > Sign Out), wait a few minutes, and sign back in. Sometimes the sync gets stuck and needs a fresh start.

If you see a lock icon next to a song in iTunes, it's DRM-protected and won't transfer through wired sync. Use iCloud Music Library instead, or remove the protection as described above.

Switching between sync methods

You can use both iCloud Music Library and wired sync on the same phone, but they can conflict. If you turn on iCloud Music Library and then also plug in to sync, iTunes may ask whether you want to keep both methods active. Generally, pick one and stick with it.

If you were syncing through iTunes and want to switch to iCloud Music Library, turn on Sync Library in Settings > Music first. Your synced songs stay on your phone. Then you can stop plugging in to sync — new songs added to iTunes will appear automatically through iCloud.

Frequently Asked Questions

Can I sync songs from iTunes to my iPhone without a cable?

Yes, if you have Apple Music or iTunes Match. Turn on iCloud Music Library in Settings > Music, and songs from your iTunes library sync automatically over Wi-Fi or cellular. If you don't have a subscription, you need to plug in with a cable.

Will my iTunes songs stay on my iPhone if I cancel Apple Music?

Songs you purchased from iTunes stay on your phone. Songs that Apple matched from your library (songs you didn't buy from iTunes) disappear when your subscription ends. To keep matched songs, you need iTunes Match specifically, not just Apple Music.

What happens to songs I download on my iPhone — do they sync back to iTunes?

No. Wired sync is one-way, from your computer to your phone. Songs you download in the Music app on your iPhone stay only on that phone. If you want them in iTunes on your computer, you have to add them there manually.

Can I sync songs from multiple computers to one iPhone?

With wired sync, no — you can only sync from one computer at a time. If you plug into a different computer, iTunes will ask whether you want to replace your current library. With iCloud Music Library, all your computers and devices sync to the same library automatically.

Why are some of my iTunes songs showing a lock icon?

That's DRM protection on older iTunes purchases. These songs won't transfer through wired sync, but they will work with iCloud Music Library. If you want to move them without iCloud, you can burn them to a CD and re-import them as unprotected files.
