Kapell

Grooves.
Radio you can steer.

Grooves are endless stations you steer. Songs are picked by their connections: artists, producers, engineers, samples and more. Leave it running all night, or steer it as it goes.

Groove is in the knobs.

Most radio is a black box: it decides, you skip. And scrolling through hundreds of stations and playlists to find the right one is a chore of its own. A Groove starts playing in one click, then listens back, so when your mood turns, the music turns with it.

Back‑seat driving, encouraged.

Grab the wheel whenever you like. Every nudge turns the Groove, starting with the next song.

  • Not this song
  • Not this artist
  • Not this era
  • More like this
  • Wrong direction
  • Shake it up
  • Undo

None of it sticks. Steering lasts as long as the Groove does. Wave off an artist on a grumpy Tuesday and they're back next time, because every new Groove starts with a clean slate.

Follow the liner notes.

A Groove walks out from where you started, along the people and places on the records. Two records that share a producer are close. Two that share a label with thousands of others barely touch. It's the same credit data Kapell shows beside every song as it plays, drawn from MusicBrainz and other open sources (how enrichment works).

The course sets how wide the lane is.

Change it any time from the steering panel.

Liner‑note nerd questions.

How does it pick the next song?

It follows the credits out from your seeds: who produced, mixed, engineered, played on and wrote the record, plus the studio, the label and the samples. Every song comes with its path, so “why this?” always has an answer.

Won't everything route through one mastering engineer?

No. Someone credited on 1,400 albums says very little about any one of them, so they barely count. A producer with a short, particular discography counts for a lot. Compilations and DJ mixes count for less, too.

Will it drift into another decade?

Only as far as you let it. A Groove keeps to the era it started in, and the course sets how far it roams: Close orbit stays near, Surprise goes looking.

Will skipping an artist ban them for good?

No. Steering only lasts as long as the Groove it was pressed in, so a bad mood today doesn't follow you into tomorrow's listening. If you want something to stick, that's what the Favorite heart is for.

Does my listening history leave my device?

To plan the next few songs, a Groove sends what you've played recently with its request. Kapell's server reads it and keeps none of it: it never reaches logs or analytics. Your Listen Log stays on your devices.

Does it work with Remote?

Yes. Start a Groove on your laptop or iPhone and the Mac on the hi‑fi plays it, steering and all. The receiving Mac needs Kapell 1.7 too.

What does it cost?

Nothing extra. Grooves come with Kapell 1.7, a free update like every other.

Coming in 1.7
