DJ software, head to head
Lexicon vs Mixed In Key.
These are not competing products doing the same job. Lexicon organises a collection and moves it between DJ apps; Mixed In Key analyses tracks and writes key, energy and cue points into the files. This compares them on what each is for, so you can tell which one your library actually needs — or whether you want both.
Choose Lexicon if
- You run more than one DJ app and need one library that stays in sync with all of them
- Your collection has accumulated duplicates, broken paths and inconsistent metadata that need cleaning up
- You want your own tag vocabulary rather than a fixed set someone else chose
- A subscription is acceptable, or the lifetime option is worth the larger one-time cost
Choose Mixed In Key if
- You want harmonic key detection and an energy rating written straight into your files
- You would rather buy once than subscribe
- Your DJ app already manages the library well and you only need better analysis feeding it
- You mix harmonically and want a wheel that shows what goes with what

Where Lexicon wins.
If these match how you DJ, Lexicon is your answer.
Moves libraries between DJ apps
Exports to Rekordbox, Serato, Traktor and Engine plus others, so a collection built in one app is not trapped there.
Cleanup and metadata repair
Finds duplicates and repairs inconsistent metadata across a collection, which is the work nobody wants to do by hand.
Cloud sync and mobile on paid plans
Paid tiers add sync across devices and a mobile app, so the library is reachable away from the main machine.
Where Mixed In Key wins.
If these match how you DJ, Mixed In Key is your answer.
One-time purchase
Bought once rather than rented, which over several years is the cheapest option in this comparison.
Energy rating and harmonic wheel
Rates tracks 1-10 for energy and shows harmonically compatible keys, which is the pairing most DJs actually use.
Writes into the files themselves
Results are stored in the file tags, so every DJ app reads them without a bridge or an export step.
