Frequently Asked Questions

MusicZen v2 organizes MP3, FLAC, WAV, M4P, OGG, and more. (Our older v1.x app only read MP3 — multi-format support is one of the biggest changes in the v2 rewrite.)

No — MusicZen reads your existing tags to rename and organize files into the right folders, it doesn't write or repair tag data. If your files have incomplete or corrupted metadata, clean them up first with a free tool like Mp3tag (Mac/Windows) or Kid3 (Linux) before organizing.

Free (v2 Basic) covers everything most people need: organizing MP3, FLAC, WAV, M4P, OGG & more into pre-defined folder structures, and it works with large libraries. Pro (currently in development) adds selecting specific file types to organize, custom duplicate handling, custom folder/file-name structures, a task report, and activity/error logs. See the Pricing section for the full comparison.

Pro is still in development. Buying a Founder License today locks in the discounted Founder price ($16 vs. $26 at launch) and guarantees you full Pro access the moment it ships — we'll email your license key automatically, no separate purchase needed.

MusicZen v2 runs on macOS (Intel and Apple Silicon Macs), Windows (portable, 64-bit and 32-bit), and Linux (x64 and ARM64) — tested on macOS Sonoma 14, Windows 11, and Ubuntu 22. This is a change from v1.x, which was Windows-only.

The Windows build is portable (no installer) and is not code-signed yet, so Windows SmartScreen may show a warning the first time you run it. To continue, choose More info → Run anyway.

MusicZen never overwrites a file. If the destination already has a file with the same name and it's the same song, the better copy is kept: if the existing file is as good or better, the new one is skipped (counted as a Duplicate); if the new one is better (for example lossless over lossy, or a higher bit rate), it's placed and the old file is moved to a MusicZen Replaced folder inside your destination. Nothing is deleted — once you've checked the new files, you can delete that folder yourself. If it's a different song with the same name, both are kept and the new one gets "(2)" in its name. The end screen shows what happened: Copied (or Moved), Replaced, Duplicates and Problems.

Yes. Every customer who bought a v1 Pro license gets a free Founder License for MusicZen Pro, as a thank-you for supporting the original version and because v1 licenses were lifetime licenses. You don't need to buy anything or sign up. When Pro launches, we'll email you a download link and license key at the address you used for your v1 purchase.

Until then, you can use MusicZen v2 Basic, which is free for everyone and doesn't need a license key. Download it here.

If your email address has changed since you bought v1, contact us and we'll make sure your license reaches you.

Used the free version of v1 but never bought a license? MusicZen v2 Basic is free for you too. To get Pro, you'll need to buy a Founder License.

Yes. Every MusicZen license — Free or Pro — is a one-time purchase that covers the current version and all future updates. No subscriptions, ever. Sign up on the download page to get notified as soon as new versions ship.

Beyond funding ongoing development, a portion of every Pro license supports Kiva.org microfinance loans.

Pro purchases are processed securely by Lemon Squeezy, our merchant of record — MusicZen never sees or stores your card details.
