Playlist Machinery vs Discover Quickly: which is better for finding new music on Spotify?
Playlist Machinery and Discover Quickly solve different problems. How each one works, what they cost, their limits in 2026, and which to pick for your use.
Playlist Machinery and Discover Quickly often come up together when people look for better ways to find music on Spotify. They don't do the same job: one automates playlists, the other helps you explore by hand. Here is how each works, as of September 2026, and which one fits which need.
Disclosure: we make Soundle, a tool in the same space. We describe both products from their own sites and documentation, and link to the sources.
Playlist Machinery in short
Playlist Machinery is the home of a family of Spotify tools by Paul Lamere. The one that matters for discovery is SmarterPlaylists; the family also includes Sort Your Music and Organize Your Music, which sort and organize playlists you already have.
SmarterPlaylists: playlists built from rules
SmarterPlaylists lets you "build complex Spotify playlists by wiring together components in a visual graph editor". You connect sources — playlists, saved tracks, recommendations — to filters, sorters and combiners, and the result is written to a Spotify playlist.
- Automatic updates: yes. The first run creates a playlist; later runs update the same one. Programs can be scheduled hourly, daily or weekly.
- Limits it states: a scheduled program runs up to 100 times before stopping, and pauses after 3 failures in a row.
- History: launched in 2015, it went offline after Spotify API changes and was rebuilt and relaunched in March 2026. Its author reports more than 9 million program runs over its first decade.
- Price: no price is listed on the site.
Its strength is power. If you enjoy designing logic — "take my saved tracks, remove what I played recently, add recommendations, shuffle" — few tools go further. Its cost is setup: you build and maintain the program yourself.
Discover Quickly in short
Discover Quickly, made by Aliza Aufrichtig and Edward Lee, calls itself "your interface for music discovery, powered by Spotify".
- How it works: a grid of album covers. Hover to preview, click to dive deeper. You can start from Discover Weekly, Release Radar, your top tracks, your playlists, saved albums, genres or related artists, and sort tracks by criteria like popularity or release date.
- Playlists: you collect the songs you click and save them to a playlist yourself.
- Automatic updates: none.
- Full playback: requires Spotify Premium, according to the app.
- Price: no pricing is shown on the site.
Its strength is speed of exploration. It is one of the fastest ways to skim through dozens of songs in a session. Its limit is that nothing happens when you are not there.
A caveat for 2026
In November 2024, Spotify restricted several Web API features for new apps, including Related Artists, Recommendations and 30-second previews. Apps that already had extended access kept it. Discover Quickly relies on several of these features; we could not confirm from the outside whether all of them still work today, so test it before relying on it.

Which one should you choose?
- You want to dig for music tonight → Discover Quickly. Preview fast, keep what you like.
- You want a playlist that rebuilds itself from your own logic → SmarterPlaylists. Expect to spend time designing the program.
- You want a playlist that renews itself and keeps your favorites, without designing rules → neither is built exactly for that.
Where Soundle fits
Soundle sits between the two. Like SmarterPlaylists, it updates a Spotify playlist on a schedule; unlike it, there is no program to build. You pick up to 5 artists or tracks, a size (15, 25 or 50) and a rhythm, and each refresh renews part of the playlist — 8 of 25 songs by default — while keeping the songs you pin, like, add or play most.
It is less flexible than a rules engine and less hands-on than Discover Quickly. It is built for people who want discovery to keep happening without doing either. The free plan includes 2 stations with weekly refreshes; for an honest list of its limits, read is Soundle worth it?.
