BTR AMP
You don’t need iTunes to put music on an iPhone. Install a music player app that accepts files directly — then transfer over Wi-Fi from any browser, connect a cloud drive like Google Drive or OneDrive, pull from an SMB network share, or AirDrop from a Mac. Your files keep their folders, tags, and quality.
iTunes (now Finder sync on macOS, the Apple Devices app on Windows) assumes your library lives in Apple’s ecosystem and syncs as a mirror. If your music is folders of MP3 and FLAC files, that model fights you. The methods below treat your music as what it is — files — using BTR AMP (free) as the player. The same ideas apply to any app that accepts file imports.
Which method should you use?
| Method | Best for | Keeps folders? | Needs a computer? |
|---|---|---|---|
| Wi-Fi Transfer (browser) | A few albums, zero setup | No | Yes |
| WebDAV (CyberDuck) | Moving a whole library | Yes | Yes |
| SMB network share | Libraries on a NAS or shared PC | Yes | Yes |
| Google Drive / OneDrive | Music already in the cloud | Yes | No |
| AirDrop | A quick album from a Mac | Yes | Mac |
Method 1: Wi-Fi transfer from your browser (easiest)
Nothing to install on the computer — the app runs a small web page on your local network.
- In BTR AMP, open Connect → Wi-Fi Transfer.
- Tap Start Wi-Fi Transfer and note the Web Browser URL it shows.
- On your computer (same Wi-Fi network), open that URL in any browser.
- Drag your music files in.
Best for a few files or one album at a time — this route doesn’t preserve folder structure.
Method 2: WebDAV for a whole library
The fastest reliable way to move thousands of files with folders intact:
- In BTR AMP, open Connect → Wi-Fi Transfer and note the WebDAV URL.
- On your computer, install the free CyberDuck and connect to that URL.
- Drag entire folder trees across; progress is shown per file.
(The WebDAV clients built into Windows and macOS are unreliable for this — use CyberDuck.)
Method 3: SMB network share
If your music lives on a NAS or a shared folder, the phone can pull directly from it:
- In BTR AMP, open Connect → Add Account → Windows SMB.
- Enter the address (e.g.
smb://server-name/share-name) and your credentials. - Browse to your music and tap the download icon next to any file or folder — queue as much as you like.
Works with Windows, macOS, and Linux shares, and it’s the best hands-off option for big transfers.
Method 4: Google Drive or OneDrive
If your collection is already in the cloud, skip the computer entirely:
- In BTR AMP, open Connect → Add Account and pick Google Drive or OneDrive.
- Sign in, browse to your music, and tap download on files or whole folders.
Folders are preserved, and downloads continue in the background. Dropbox and other providers work through the iOS Files app the same way.
Method 5: AirDrop from a Mac
For a quick album: select the folder on your Mac, AirDrop it to your iPhone, and choose BTR AMP when iOS asks which app should receive it. Send one album at a time — iOS shows no progress while it hands the files over.
What about a USB cable?
Still possible without the iTunes library model: connect the cable and use Finder (Mac) or the Apple Devices app (Windows) to drop files into the player app’s file-sharing area. It works when there’s no Wi-Fi, but it can’t browse folders, so wireless methods above are usually better.
FAQ
Will my FLAC files work? Yes — this is exactly the case where skipping iTunes matters, since the Music app won’t play FLAC at all. See how to play FLAC on iPhone.
Do transfers lose quality? No. Every method above copies your files bit-for-bit — no conversion, no re-encoding.
Can I get the music back off the phone later? With BTR AMP, yes — the same connections move files out as well as in. Your library is never locked in.
