# Examples

- `Favourite Pop`: A playlist
  containing all favourite items of the genre pop.
  ```
  Id: Favourite Pop
  Name: Favourite Pop
  Program: |
    (and (is-type "Audio") (is-favorite) (is-genre "pop" (genre-list)))
  ```
- `Electro Swing`: A playlist containing all items
  which have a genre that contains "electro" and a
  genre that contains "swing". It will only include
  albums and single tracks.
  ```
  Id: Electro Swing
  Name: Electro Swing
  Program: |
    (let
      (g (genre-list))
      (and
        (or
          (is-type "Audio")
          (is-type "MusicAlbum"))
        (is-genre "electro" g)
        (is-genre "swing" g)))
  ```

- `All of Seeed`: A playlist containing all items by artist `Seeed`,
  useless, since you also can just navigate to the artist to play all
  their songs, but a good example.
  ```
  Id: Seeed
  Name: Seeed
  Program: |
    (let
      (parent
        (invoke-generic *item* "FindParent" nil (list "MediaBrowser.Controller.Entities.Audio.MusicArtist, MediaBrowser.Controller")))
      (cond
        ((null parent) nil)
        (t (string= (car (getitems parent "Name")) "Haller"))))
  ```
  or simplified with definitions contained in the preamble:
  ```
  Id: Seeed
  Name: Seeed
  Program: |
    (let
      (parent
        (find-parent "MediaBrowser.Controller.Entities.Audio.MusicArtist, MediaBrowser.Controller"))
      (cond
        ((null parent) nil)
        (t (string= (car (getitems parent "Name")) "Seeed"))))

  ```

- `Artists`: A playlist including everything from a list of artists.
  ```
  Id: Artists
  Name: Artists
  Program: >-
    (begin
      (define *include-artists* '(
        "seeed"
        "juli"

            ;; the `(and (find-artist)` is here to prevent null violations.
            (and (find-artist) (string= i (lower (get-name (find-artist))))))
          *include-artists*)))
