Try to get and parse spotify playlists
spotify:playlist:7hGGMcWOPgXj2qFw5DQyXP - likes_2021
spotify:playlist:2etpNxusBBUoXoxb3BOsF3 - likes_2020
Todo:
----
- extract the wanted info (track name, artist(s), picture url,
track URI, etc) more elegantly
- handle multiple artists
- access token timeout? check if check is needed
- find alternative to the kludge to prevent skipping first list
Done:
----
2021-04-04: handle longer playlists
Outline:
-------
- get playlist
- extract playlist metadata
- create playlist dictionary
(---)
- extract tracks & store
- check if done, else iterate over next set of tracks
(---)
- store completed list, clean up.
Playlist format:
---------------
Playlist = {'name': '',
'image': '',
'uri': '',
'tracks': [
{'artist': '',
'name': ''
},
{'artist': ''
'name': ''
}
]
}
