Get Recommendations

Recommendations are generated based on the available information for a given seed entity and matched against similar artists and tracks. If there is sufficient information about the provided seeds, a list of tracks will be returned together with pool size details.

For artists and tracks that are very new or obscure there might not be enough data to generate a list of tracks.

Important policy note

Request

  • limit
    integer

    The target size of the list of recommended tracks. For seeds with unusually small pools or when highly restrictive filtering is applied, it may be impossible to generate the requested number of recommended tracks. Debugging information for such cases is available in the response. Default: 20. Minimum: 1. Maximum: 100.

    Default: limit=20Range: 1 - 100Example: limit=10
  • market
    string

    An ISO 3166-1 alpha-2 country code. If a country code is specified, only content that is available in that market will be returned.
    If a valid user access token is specified in the request header, the country associated with the user account will take priority over this parameter.
    Note: If neither market or user country are provided, the content is considered unavailable for the client.
    Users can view the country that is associated with their account in the account settings.

    Example: market=ES

        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. Duplicate tracks (e.g. the same track from a single and an album) are rated independently. Artist and album popularity is derived mathematically from track popularity. Note: the popularity value may lag actual popularity by a few days: the value is not updated in real time.
