A free, independently curated list of tools for building mixes and playlists.

Study how professional DJs sequence a set here - it's a masterclass in pacing and transition that translates directly to structuring a SoundStory collection.

Once you're ready to build original transitions or layer ambient textures between tracks - the kind of thing that makes a SoundStory mix feel custom rather than just sequenced - this is the tool that supports it.
Their cinematic and atmospheric catalogue overlaps closely with SoundStory's own aesthetic, making it a natural source if you need licensed music for anything beyond the collections themselves.

Free and simple enough to trim, fade, and stitch together a rough mix file for a new collection before you've invested in anything more advanced.
When you've got one perfect track that nails a film's mood, this filters by tempo and energy to find others that will sit alongside it without breaking the collection's flow.

The easiest entry point if you're curating tracks but have never mixed before - good for turning a SoundStory collection into a blended listening experience without a steep learning curve.

Djoid's Graph Playlist and Scatter Map visualise your tracks by harmony, energy, and emotion so you can rediscover forgotten gems that fit a theme like Blade Runner or Severance without manually re-listening to everything.

If you ever want to pair a mix with video content (a YouTube upload, a Reel), this keeps you covered on copyright without hunting for royalty-free tracks one by one.
Start here when a film's mood doesn't map to an obvious genre; it helps you find the adjacent micro-genre that actually captures a world like Severance's corporate dread or Dune's tribal desert atmosphere.

If you're moving from casual curation into properly DJ-mixed sets, this is the tool that makes your transitions sound intentional instead of accidental.
Use this to dig into a composer's or score's critical reception and community discussion, which is often where you'll find the specific tracks or adjacent artists a SoundStory collection should include.

If you want to turn a static playlist into a properly mixed, seamless listening experience, this is the standard tool for prepping and sequencing those tracks professionally.

An alternative to Rekordbox worth trying if you're already comfortable with a more visual, beginner-friendly interface for building your first mixed sets.
Before you sequence a collection, check this to make sure the tracks you're placing back-to-back won't clash in key and pull a listener out of the mood you've built.

Use this to see what music actually played in a specific scene before you diverge from it — knowing the "official" reference point makes your inspired-by curation more intentional, not less original.
