Why platforms disagree about genre
Every catalog runs its own taxonomy. One platform's Electro is another's Dance and a third's Electronic. Genre is also declared by whoever delivered the release, so the label's own choice at upload time carries through into the stores, which is why plenty of releases sit under a genre nobody would pick by ear.
For artists this matters commercially. Genre drives editorial playlist routing, algorithmic neighbours, chart eligibility and the shelf your release lands on in every store. Seeing what the platforms currently believe is the first step to fixing it on your next delivery.
Using genre research on your own releases
The practical move is to look up the releases you want to sit beside. Search five or six reference tracks that share your audience, note the genre each one carries, and use that as the genre you declare when you deliver. You are not guessing at what fits, you are matching what the platform already groups together.
For a catalog rather than a single, tagging by hand stops being realistic. TrackTag listens to each track and assigns genre, sub-genre, mood, instrumentation, BPM and key across hundreds of files in one pass, which is the same job done at catalog scale.
What the result shows
The genre tags on the release, Apple's primary genre for the same release, the tempo in BPM where the catalog carries it, duration, label and release date. Between the release genre and the Apple genre you get a fair picture of how the track is filed across services.
Results come from Deezer's public catalog and Apple's public album data, so anything commercially released and distributed to streaming should be found. Unreleased tracks, private uploads and releases that never reached streaming will not appear.
