+
+
+Hello everyone! I'm **Antonio Giordano**, and I'm excited to share the results of my **Google Summer of Code 2025** work on Mixxx. We've introduced **true multi-genre support** with smart autocompletion, a cleaner editing experience, and tools to migrate your existing library without breaking your flow.
+
+### Project Vision & Evolution
+
+Our goal was to give DJs flexible, reliable control over genres beyond a single free-text field. In earlier versions, you could type multiple genres (e.g., `Dance/Electronic/House`), but Mixxx treated that as **plain text**. It couldn't understand or manage individual tags.
+
+To get this right, we started with a **solid multi-genre foundation** that's fast, consistent, and future-friendly. This foundation paves the way for richer features like hierarchical genres.
+
+### What's New
+
+#### Single-Track Genre Editing (Chip UI + Autocomplete)
+
+The **Track Properties** dialog now shows genres as compact **chips** with a white **x** to remove, plus **autocomplete** to add existing genres quickly.
+
+- **Clean look & feel:** compact chips, thin scrollbar, readable contrast.
+- **Autocomplete:** type a few letters and pick from existing genres.
+- **No more long strings:** add/remove individual genres directly.
+- **Always consistent:** the track table shows human-readable names everywhere.
+
+**Note:** If you type a genre that doesn't exist yet, Mixxx keeps it as a literal. You can map it later using the Orphan Genres tool (see below).
+
+#### Multi-Track Editing (Experimental)
+
+You can now edit genres across multiple tracks in one go (experimental):
+
+- **Common view:** shows the **intersection** of genres shared by all selected tracks.
+- **Batch operations:** add or remove genres for the whole selection.
+- **Safe by design:** unique per-track genres are preserved.
+
+#### A Smarter Library: Tree, Counts, and Drag & Drop
+
+Genres now live in a **tree**. Each node shows **track count** and **total duration**. When you select a track, the genres it belongs to become **bold** in the tree crate-like ergonomics for quick navigation.
+
+- **Drag & drop:** drag tracks from the Tracklist onto a genre to assign it.
+- **Quick menu:** right-click a track then **Genres** to (de)select on the fly.
+- **Rename safely:** renaming a genre changes the **name**, not the ID, so tracks keep their associations.
+
+#### Clean Migration: "Orphan Genres"
+
+If your library contains free-text genres, Mixxx detects **orphans** and helps you clean them up:
+
+- Right-click the **root** of the genre tree then **Edit Orphan Genres**.
+- **Add** a new genre or **Link** a string to an existing one.
+- Multi-word strings appear as both a full string *and* individual tokens; add the full string first if you want to keep it as a single genre.
+
+
+### Why This Matters for DJs
+
+**Before:**
+
+- One free-text field. No understanding of individual genres.
+- No autocomplete.
+- Editing meant retyping a whole string.
+- Inconsistent naming ("Electronic" vs "electronic").
+- No real bulk editing.
+
+**Now:**
+
+- **True multi-genre:** each tag is a first-class citizen.
+- **Autocomplete:** fast, consistent tagging.
+- **Visual editing:** add/remove with chips.
+- **Bulk-friendly:** multi-track editor (experimental) for common operations.
+- **Library-aware:** a genre tree with counts, duration, and drag & drop.
+- **Backwards-compatible:** your library keeps working; migrate at your pace.
+
+### How to Use It
+
+#### Single Track
+
+1. Right-click a track, **Properties**.
+2. In **Genre**, start typing and pick from autocomplete.
+3. Click the **x** to remove a tag.
+4. **OK** or **Apply** to save.
+
+#### Multi Track (Experimental)
+
+1. Select multiple tracks then right-click then **Properties**.
+2. See the **common** genres across the selection.
+3. Add or remove tags in bulk.
+4. Save: Mixxx preserves track-specific genres.
+
+#### Clean Up Old Text Tags
+
+1. In the genre tree, right-click the **root** then **Edit Orphan Genres**.
+2. **Add** new genres or **Link** strings to existing ones.
+3. Repeat as needed, your sets keep running.
+
+#### Under the Hood (Brief)
+
+- **Stable IDs** for genres and a fast **join table** (`genre_tracks`) so filtering and counts are snappy.
+- A central **Genre DAO** (data access layer) that maps between IDs and names and normalizes raw data.
+- The UI always shows **human-friendly names**; the storage format stays robust behind the scenes.
+
+### Demo video (quick tour)
+

+*This short video bundles all demos: single-track tag chips, multi-track bulk edit, the Genre Tree with drag-and-drop and **F2** rename, and the **Edit Orphan Genres** flow*
+
+### What's Next
+
+This foundation unlocks a lot of potential. Based on community input, we're exploring:
+
+- A **full hierarchical** genre tree with multi-level editing.
+- **Fuzzy autocomplete** to handle typos gracefully.
+- **Search** that also matches genre names.
+- Smarter **import/export** of genre structures (share your taxonomy).
+- Better **metadata export** across formats for multi-genre fields.
+- Optional **auto-conversion** of known strings to stable IDs on import.
+
+### Thank You
+
+Huge thanks to the Mixxx mentors and community for guidance, reviews, and real-world feedback. This is a big step forward, and we'll keep refining it together.
+Please try it and tell us what works for you.
