Saved Album Tracks filtered by Last.fm top artists

[BuckeyePay]

I am having a bit of logic problem. I am trying to create a playlist of tracks from my saved albums from a select number of my top artists from last.fm. What I don't know is how to get from artists to tracks, or if that is even possible.

let artists = Lastfm.getTopArtists({
user: 'ChiliDog',
period: '5year',
limit: 25
});

not sure how to use this with getSavedAlbumTracks or getSavedAlbums based up the last.fm artists, or that is even something I can do.

1. Default Lastfm.getTopArtists don't give top for 5year period. Because last.fm API have only such parameters: overall, 7day, 1month, 3month, 6month, 12month. But goofy have getCustomTop.
2. In order to keep albums only from top artists, we need to use removeArtists with invert = true.
3. In case with saved albums, tracks are located in response. Thus need to only map loop. With general albums probably require additional requests.

function createPlaylistFromSavedAlbumsByTopArtists() {
  let savedAlbums = Source.getSavedAlbums()
  let topArtists = Lastfm.getCustomTop({
    type: 'artist',
    user: KeyValue.LASTFM_LOGIN,
    from: '2022-01-01',
    to: '2022-12-31',
    count: 25,
  })
  Filter.removeArtists(savedAlbums, topArtists, true)

  let albumsTracks = savedAlbums.map(a => a.tracks.items).flat()
  Playlist.saveWithReplace({
    name: 'Saved Albums From Top Artists',
    tracks: albumsTracks
  })
}
