Tracklist Comparison

Compare your saved tracklist against the latest Discogs data. This helps you recover missing tracks, fix errors, or update outdated information.

When to Use This

Use tracklist comparison when:

• Your tracklist seems incomplete
• Track titles look wrong
• You want to verify your data matches Discogs
• A release was updated on Discogs with corrections

Starting a Comparison

From the album editing window or detail flyout:

1. Click Fetch Tracks from Discogs (or similar)
2. DeepGrooves retrieves the current tracklist from Discogs
3. Tracks are compared against your saved data
4. Results display in a diff view

Understanding the Diff

The comparison shows each track with a color-coded status:

Color	Status	Meaning
🟢 Green	Added	Track exists in Discogs but not in your copy
🔴 Red	Removed	Track exists in your copy but not in Discogs
🟠 Amber	Modified	Track exists in both but details differ
⚪ Gray	Unchanged	Track matches exactly

Diff Details

Added Tracks (Green)

These tracks are on Discogs but missing from your saved data. Common reasons:

• Tracks weren't imported originally
• Bonus tracks or hidden tracks
• Data added to Discogs after your import

Removed Tracks (Red)

These tracks are in your saved data but not on Discogs. Common reasons:

• Track was removed from Discogs (rare)
• You added tracks manually
• Different pressing has different tracks

Modified Tracks (Amber)

These tracks exist in both but have differences:

• Title spelling changed
• Duration corrected
• Side/position updated

Click a modified track to see exactly what changed.

Summary Badges

At the top of the diff view, badges show totals:

• +N new — Tracks to be added
• −N removed — Tracks to be removed
• ~N changed — Tracks with modifications

If everything matches, you'll see "Tracklists are identical."

Selecting Changes

Check the box next to each change you want to apply. Options:

Button	Action
Select All	Apply all changes
Select None	Apply no changes
Additions Only	Only add new tracks (don't remove or modify)

Use Additions Only when you want to recover missing tracks without affecting what you already have.

Applying Changes

Click Apply Selected Changes to update your tracklist:

• Checked additions are created
• Checked removals are deleted
• Checked modifications are updated

Changes save immediately.

Canceling

Click Cancel or close the diff view to exit without making changes. Your tracklist remains unchanged.

No Differences Found

If your tracklist matches Discogs exactly, you'll see a message: "Tracklists are identical. No changes needed."

Best Practices

• Review before applying — Look at what's changing before clicking Apply
• Use Additions Only — When you just want to fill gaps
• Check modified tracks — Make sure the Discogs version is actually better

Note on Different Pressings

Different pressings of the same album may have different tracklists:

• Bonus tracks on some editions
• Different track order
• Regional variations

The comparison uses your album's specific Discogs release ID, so it should match your pressing.
