You don't need to download your files and re-upload them in the release. You can transfer them directly from MP3-Tag into your release.
Here's how:
- Edit your files in Tools → MP3-Tag and save them.
- Start a new release or open an existing one.
- In the Release Wizard (Step 1), you'll find the section "Or select audio files from MP3-Tag".
- There you'll see files that match the track. Tick the checkbox next to the files you want.
- Continue through the wizard. The files will be added to the release.
Replace an audio file: For a track that has already been created, you can replace the file with a file from MP3-Tag using "File from MP3-Tag …".
What happens:
- The file is moved to the release including its tags.
- If the file contains an ISRC, it will be entered for the track as your own ISRC (Step 2 in the wizard).
- The file is then no longer available in MP3-Tag. You'll find it there in the section "Used in releases", but you can no longer edit it.
Don't see any files? Then you have no free files in MP3-Tag. Use Open MP3-Tag to go straight there.
