Frequently asked questions is currently still in beta, so you can use it for free until we launch our final product. When that happens you will have the choice to either pay for a subscription, or stop using If you stop using, your Spotify playlists you created will stay intact. The only thing is they will not continue to update automatically.
The first purpose of is to generate a Best Of playlist, that means a playlist compiling the most popular tracks for selected artists and labels. So you can generate a playlist about one or multiple artists, a playlist about one or multiple labels, or a combination of both: a playlist with the most popular tracks from artists A and B released on label C.

Based on our users feedbacks, has evolved and it is now also possible to filter the tracks based on many parameters such as the release date, the energy of the track, the tempo, ... Also you are not limited to the most popular tracks. You can change your selection criteria, to get for example the most danceable tracks, or the tracks with the highest tempo, or one of the many other criteria available. Finally the selected tracks for your playlist can also be sorted as you wish. The default metric for sorting is the popularity, but you might decide to sort by tempo, release date, energy, ...

The possibilities are pretty much infinite now.
Yes, once the playlist is generated, feel free to go on Spotify to change it as you wish. We currently do not offer a way to do it directly on, but if you need this, please let us know.
We need you to connect your Spotify account in order to be able to create your playlist, and update it. We ask for many permissions, including permissions related to public and private playlists. This way we will be able to edit your playlists whether you made it public or private. You have our word we will not alter any of your playlists you did not link to
The first step is to get all tracks from Spotify (using the Spotify API) for the artists and labels matching your filters. Once we have all the tracks, we will filter them to keep only those matching your criteria (release date, tempo, energy, ...). After that we remove all the duplicates (based on the isrc code), select the wanted tracks (for example the most popular ones) and finally sort the tracks with the sorting option you selected.
The popularity is a metric defined by Spotify as follows: The popularity of a track is a value between 0 and 100, with 100 being the most popular. The popularity is calculated by algorithm and is based, in the most part, on the total number of plays the track has had and how recent those plays are. Generally speaking, songs that are being played a lot now will have a higher popularity than songs that were played a lot in the past. Note that the popularity value may lag actual popularity by a few days: the value is not updated in real time.
Yes, even though this is a big advantage of, we understand you might want to keep control of what is generated and when. You have two options. The first one is to choose the frequency 'Manual' when you create your playlist. This way the playlist will only update when you trigger it manually from your dashboard. The second way is to set it on pause from your dashboard. In that case the playlist will stop being updated automatically. You can get it back to play at any time to restore the previous frequency.
These are metrics provided by Spotify for each tracks and defined as follows:
  • Acousticness: A confidence measure from 0 to 100 of whether the track is acoustic. 100 represents high confidence the track is acoustic.
  • Energy: Energy is a measure from 0 to 100 and represents a perceptual measure of intensity and activity. Typically, energetic tracks feel fast, loud, and noisy. For example, death metal has high energy, while a Bach prelude scores low on the scale. Perceptual features contributing to this attribute include dynamic range, perceived loudness, timbre, onset rate, and general entropy.
  • Instrumentalness: Predicts whether a track contains no vocals. "Ooh" and "aah" sounds are treated as instrumental in this context. Rap or spoken word tracks are clearly "vocal". The closer the instrumentalness value is to 100, the greater likelihood the track contains no vocal content. Values above 50 are intended to represent instrumental tracks, but confidence is higher as the value approaches 100.
  • Liveness: Detects the presence of an audience in the recording. Higher liveness values represent an increased probability that the track was performed live. A value above 80 provides strong likelihood that the track is live.
  • Speechiness: Speechiness detects the presence of spoken words in a track. The more exclusively speech-like the recording (e.g. talk show, audio book, poetry), the closer to 100 the attribute value. Values above 66 describe tracks that are probably made entirely of spoken words. Values between 33 and 66 describe tracks that may contain both music and speech, either in sections or layered, including such cases as rap music. Values below 33 most likely represent music and other non-speech-like tracks.
  • Tempo: The overall estimated tempo of a track in beats per minute (BPM). In musical terminology, tempo is the speed or pace of a given piece and derives directly from the average beat duration.
  • Valence: A measure from 0 to 100 describing the musical positiveness conveyed by a track. Tracks with high valence sound more positive (e.g. happy, cheerful, euphoric), while tracks with low valence sound more negative (e.g. sad, depressed, angry).
