  title: Last.fm Web Services API (2.0) Album API
  version: '2.0'
  description: 'The Last.fm (AudioScrobbler) Web Services 2.0 API provides programmatic access to

    music metadata, charts, geo-listening data, tags, user listening history, and

    scrobbling. The API is method-dispatched: every request targets the single endpoint

    `https://ws.audioscrobbler.com/2.0/` and identifies the operation via the `method`

    query/body parameter (e.g. `method=track.getInfo`).


    Read methods accept `GET`; write methods (scrobbling, tagging, love/unlove, session

    management) require `POST` with an authenticated session key and a signed

    `api_sig` parameter (MD5 of sorted params + shared secret).


    Responses default to XML; pass `format=json` for JSON.
