lastfm

Scrape LAST.FM user's playlists to SQLite.
Docs: https://lastfm.readthedocs.io/en/latest/

Usage

pip install lastfm-to-sqlite

Now run CLI:

lastfm export 244ec3b62b2501514191234eed07c75d lastfm_dump.db --user Way4Music

That will use (or create) a SQLite database called lastfm_dump.db and a table called playlist to export user's entire playlist.

To scrape specific dates, use --start_date and --end_date:

lastfm export 244ec3b62b2501514191234eed07c75 lastfm_dump.db --user way4music --start_date 2021-08-21 --end_date 2021-09-01

Python-based API works like this:

from lastfm import LastFM

# specific date, ommit start_date and end_date to download all tracks
api = LastFM(
    api="244ec3b62b2501514191234eed07c75d",
    username="way4music",
    start_date="2021-08-21",
    end_date="2021-09-01"
)
data = api.fetch()
song = next(data)
print(song)
container = []
for item in data:
    container.append(item)

Duplicated requests

https://github.com/hp0404/lastfm/blob/2ab7c7c88a17c44bd641cfd3fb95eda8da7061a7/lastfm/export.py#L69-L75

Could use export_page here for r.json() and change page value after: params["page"] += 1, thus avoiding duplicate request.

Something along the lines:

 r = requests.get(URL, params=params) 
 r.raise_for_status() 
 data = r.json()
 meta = get_metadata(data)
 yield from export_page(data)
  
 params["page"] += 1 
 with requests.Session() as session: 
     yield from fetch(session, params, meta)
