  Last.fm publishes no public pricing for its 2.0 Web Services. The API has a single
  free non-commercial tier obtained by registering an API account at
  last.fm/api/account/create. Commercial, redistribution, or research/academic use
  requires a private commercial use agreement negotiated via partners@last.fm. The
  values below reflect the documented Reasonable Usage Cap (100 MB storage) and the
  per-origin rate guidance (5 req/sec) from the Terms of Service.

      personal/hobby use of the read methods and authenticated user-scoped write

      attribution and prohibits sub-licensing.
