Research from DJ TechTools, Serato forums, Digital DJ Tips, Heavy Hits, and working DJs — distilled into the principles that drive DJOrganizer's design.
How many genre folders should a DJ have? Too few and you're scrolling through hundreds of tracks. Too many and you're scrolling through folders instead of music.
8–15 top-level genre folders is the sweet spot. Start broad — add subgenres only when a folder exceeds 75–100 tracks. One DJ managing 8,000 tracks uses ~10 major genres with 50 sub-genres across 300 playlists.
Across multiple expert sources, these categories appear repeatedly as the foundation for versatile DJs:
| Genre | Includes | Typical BPM |
|---|---|---|
| House | Deep, Tech, Afro House, Progressive, Vocal | 120–130 |
| Amapiano | Log drums, piano melodies, deep bass | 112–115 |
| Afrobeats | Burna Boy, Wizkid, Tems — distinct from Amapiano | 95–110 |
| Dancehall | Current + classic dancehall, soca crossover | 95–110 |
| Hip-Hop / R&B | Current, old school, trap | 70–100 |
| Latin | Reggaeton, dembow, salsa, bachata, Latin house | 90–130 |
| Pop / Top 40 | Current radio hits + throwbacks | 100–130 |
| Funk / Disco / Soul | Classic funk, nu-disco, boogie | 110–125 |
| Electronic / Techno | Melodic, peak time, minimal, trance | 125–145 |
| Classics | Cross-genre crowd pleasers by era | Varies |
Keep each crate to 50–75 songs (max 125). If a folder gets bigger, split it into subgenres. This forces you to curate instead of hoard. — Heavy Hits
Genre tells you what to play. Energy tells you when to play it. Every serious DJ tags energy — the debate is only about how.
Works in Rekordbox, Serato, and Traktor. Simple, universal, portable.
| Rating | Energy | When to Play |
|---|---|---|
| ★ | Background | Home listening only |
| ★★ | Low | Warm-up, dinner, arrivals |
| ★★★ | Mid | Building momentum, transitions |
| ★★★★ | High | Prime time, dance floor filling |
| ★★★★★ | Peak | Peak-time bangers, crowd eruption |
Used by DJ Danny James in Rekordbox as a visual layer on top of star ratings.
DJ TechTools identifies 7 energy levels: Sunrise → Kickin' It → Warm-Up → Primetime → Bangin' → Trippin' → Late Night. These become parent folders with genre subfolders inside each.
We combine genre-first folder structure with energy tags inside each genre. Your folders answer "what genre?" — the energy metadata answers "what moment in the set?"
Mobile DJs, wedding DJs, and anyone who plays corporate events needs to separate clean from explicit instantly. Three approaches from the field:
| Method | How It Works | Best For |
|---|---|---|
| Filename suffix | Add "Clean" or "Explicit" to filename | Any DJ software — always visible |
| Separate crates | Mirror crate structure: one clean, one explicit | Wedding/corporate DJs |
| Metadata tag | Use Comments or Grouping field | DJs who filter by metadata in software |
Always default to clean for corporate events. Only access explicit if the client specifically approves. Tag in the Comments field or use a dedicated metadata column — and always ask the client upfront.
Beyond genre and energy, experienced DJs tag tracks by the moment they're designed for. This is the layer that separates playlist DJs from set builders.
Used by Mr. Sonny James (Serato community):
From DJ TechTools and the Crossfader community:
Write "MWW [song name]" in the Comments field to remember successful transitions. During a live set, this is gold — you never forget a combo that worked.
| Approach | Levels | Best For |
|---|---|---|
| 2-level nested | Genre → Subgenre | Most DJs (recommended) |
| 3-level nested | Genre → Sub → Sub | Libraries over 5,000 tracks |
| Flat + heavy tagging | One level | Small libraries under 500 tracks |
| Energy-first | Energy → Genre | Club-focused, set-building DJs |
| Event-first | Event Type → Vibe | Mobile/wedding DJs |
Short folder names, no special characters, no emojis. USB sticks and CDJs handle weird characters poorly. Consistent capitalization throughout. Filenames: ARTIST - TITLE - REMIX standardized with MP3tag.
The key principle from Heavy Hits: "Less is more." Even with 35,000+ tracks, work from focused, curated crates of 50–75 songs during a gig. The big library is for prep; the gig crate is for performance.
