MixScout Companion — DJ Playlist Harmonic & Set Coach

Analyze music playlists for BPM, Camelot harmonic keys, transition flow, 4-track venue runs, and live drag-and-drop reordering.

Turn any open music playlist in your browser into a harmonically balanced DJ set without leaving the page. MixScout Companion opens a side-by-side DJ studio panel next to your favorite music streaming or crate-digging platform, automatically reading the currently open playlist and analyzing how well each track flows into the next. FEATURES • Instant Playlist Analysis — Open a playlist on Spotify Web, YouTube, YouTube Music, Beatport, SoundCloud, Apple Music, Deezer, TIDAL, or Bandcamp to see every track's BPM, Camelot harmonic key (1A–12B), and broad genre. • Live Transition Health & Bridge Track Finder — See at a glance which track pairs mix smoothly (🟢 Smooth), which work as tempo bridges (🟡 Bridge), and where jarring tempo or key jumps happen (⚠️ Jump). Click any transition pill to discover 3 harmonic bridge songs that connect two tracks seamlessly. • Interactive Tempo & Energy Arc Sparkline — View the visual BPM and transition trajectory of your entire playlist and click any point on the curve to jump straight to that song on the page. • Live Queue & 4-Track Venue Dealer — Deal an instant 4-song venue progression (1 · Warm-Up -> 2 · Groove -> 3 · Singalong -> 4 · Peak) with 4 distinct artists, Room Vibe filters, a Venue Sweet Spot filter (<= 5:30, no club bootlegs), and a "Played Tonight" tracker. • 3-Act Narrative Set Arranger — Preview and coach your playlist as a 3-Act DJ narrative (Act I · Warm-Up -> Act II · Peak Hour -> Act III · Cooldown) with harmonic smoothing inside each act. • Live In-Page Reorder Guide — Click any step to highlight both the track to grab (✋) and its exact drop target (🎯) right inside your open playlist tab, updating live as you drag and drop tracks. • On-Page BPM & Key Badges — Toggle inline BPM and Camelot key badges directly onto track rows inside your open playlist page. • Multi-Tab Crate Collector Basket — Collect tracks across multiple tabs and streaming platforms into one unified Working Crate. • Crate Hygiene Filter & 1-Click .CSV / .M3U8 Export — Filter and highlight duplicate songs or tempo outliers on the page, or download .CSV and .M3U8 crate files directly from the side panel. • 30-Second Audio Previews & Camelot Key Filtering — Filter your playlist by compatible Camelot keys and audition 30-second previews directly in the side panel. • 1-Click Handoff to MixScout Web Studio — Send your entire detected playlist straight to mixscout.app/dashboard for deep track discovery and set preparation. • Bilingual Interface — Switch between English and Spanish (EN | ES) at any time.
