A method for making a playlist available to the public, in which the playlist comprises user-defined descriptor information. The user-defined descriptor information is entered as free form text or prose.

Embodiments of the present disclosure provide an information processing method and a device. The method includes: in response to an operation acting on a source music list, obtaining a preset number of pieces of music information from the source music list to form a target playlist, where the music information in the source music list includes identifiers, and the identifiers are used to represent an order of the music information in the source music list; sorting the music information in the target playlist according to the source music list and the identifiers, so that an order of the music information in the target playlist is consistent with the order of the music information in the source music list. In this way, a user can play songs in a target playlist selected by the user in the order in the source music list, which improves the user's listening experience.

Systems, methods, and non-transitory computer-readable media can be configured to determine popularity scores for a set of audio content items. The set of audio content items can be ranked based at least in part on the popularity scores, the popularity scores based at least in part on signals associated with a social networking system. A music chart can be generated based at least in part on the ranking.

A method of providing a group listening session to users of a messaging platform includes: receiving, at a media streaming platform, a message feed from the messaging platform; parsing, at the media streaming platform, the message feed to identify one or more commands included in the message feed, wherein the one or more commands are associated with the group listening session provided by the media streaming platform; and controlling the group listening session according to the one or more commands, each of the users being associated with a media device for participating in the group listening session.

A method, device and system for organizing media content on a computer-based system to form a playlist, wherein the device has access to a database with a plurality of music tracks and associated feature vectors including feature values representing different semantic characteristics of a music track, as well as metadata including at least one type of metadata record representing associated information about the respective music track. The playlist is determined based on a query from the client device that includes an input vector, and at least one input metadata record, using an additional similarity matrix representing a measure of similarity between different metadata records of the same type.

Systems and methods are provided for filtering at least one media content catalog based on criteria for a station library to generate a first list of candidate tracks for the station library, combining a similarity score and a popularity score for each track of the first list of candidate tracks to generate a total score for each track of the first list of candidate tracks, generating a list of top ranked tracks for the first genre, and returning the list of top ranked tracks of the first genre as part of the station library.

Embodiments described herein provide for extending media playback. In an example implementation, during playback of one or more first media items populated in a queue, a control system extends playback time of the queue. Extending playback time of the queue may involve determining when the one or more first media items will be finished playing; and before the first media items are finished playing, determining one or more second media items that correspond in substantial likeness to the one or more first media items and sending an instruction that causes the first playback device to insert the determined one or more second media items into the queue such that play time of the queue is extended.

A machine is configured to identify a media file that, when played to a user, is likely to modify an emotional or physical state of the user to or towards a target emotional or physical state. The machine accesses play counts that quantify playbacks of media files for the user. The playbacks may be locally performed or detected by the machine from ambient sound. The machine accesses arousal scores of the media files and determines a distribution of the play counts over the arousal scores. The machine uses one or more relative maxima in the distribution in selecting a target arousal score for the user based on contextual data that describes an activity of the user. The machine selects one or more media files based on the target arousal score. The machine may then cause the selected media file to be played to the user.

A system and method for making categorized music tracks available to end user applications. The tracks may be categorized based on computer-derived rhythm, texture and pitch (RTP) scores for tracks derived from high-level acoustic attributes, which is based on low level data extracted from the tracks. RTP scores are stored in a universal database common to all of the music publishers so that the same track, once RTP scored, does not need to be re-RTP scored by other music publishers. End user applications access an API server to import collections of tracks published by publishers, to create playlists and initiate music streaming. Each end user application is sponsored by a single music publisher so that only tracks capable of being streamed by the music publisher are available to the sponsored end user application.

Examples described herein relate to facilitating media item access via a media item database. For instance, a playlist may include audio tracks of a first streaming service (e.g., as uniform resource identifiers linking to streamable audio tracks). When a subscription to the first streaming service is not active, the playlist may be unplayable by a media playback system including a playback device. To play the playlist, a computing system may convert the playlist to audio tracks of a second streaming service and then send the converted playlist back to the media playback system for playback.
