;; An interface to ListenBrainz, a project to store a record of the music that
;; you listen to. The listening data, can be used to provide statistics,
;; recommendations and general exploration.
;;
;; The package can be used programmatically (e.g. from a music player) to auto
;; submit listening data `listenbrainz-submit-listen'. There are other entrypoints
;; for reading user stats such as `listenbrainz-stats-artists' or
;; `listenbrainz-listens'.
;;
;; Some API calls require a user token, which can be found in your ListenBrainz
;; profile. Configure, set or `customize' the `listenbrainz-api-token' as needed.

;; An interface to the MusicBrainz "open music encyclopedia" collection
;; of music metadata. The main entry points are `musicbrainz-search' for
;; general searches and `musicbrainz-lookup' for the more specific.
;; There are also some narrower searches such as `musicbrainz-search-artist'
;;
;; Naming follows the MusicBrainz API reasonably closely, so the official API
;; documentation can provide insight into how searching, browsing and lookups
;; are structured. MusicBrainz has it's particular taxonomy and quirks, so
;; some familiarity may be required to get useful results in some cases.
