- Files satisfying `pref` conditions will be preferred. Files not satisfying `nec` conditions will not be downloaded.  
- When using csv, provide either both a track-col and artist-col (ideally), or full-title-col in case separate artist and track names are unavailable. You can also specify --uploader-col (channel names) in that case to use as artist names whenever full-title-col doesn't contain them. Always provide a length-col or get wrong results  

Download tracks from a csv file and create m3u:
```
slsk-batchdl.exe -p "C:\Users\fiso64\Music\Playlists" --csv "C:\Users\fiso64\Downloads\test.csv" --username "fakename" --password "fakepass" --artist-col "Artist Name(s)" --track-col "Track Name" --length-col "Duration (ms)" --time-unit "ms" --skip-existing --create-m3u --pref-format "flac"
```
Download spotify playlist and create m3u:
```
slsk-batchdl.exe --spotify <url> -p "C:\Users\fiso64\Music\Playlists" --m3u "C:\Users\fiso64\Documents\MusicBee\Playlists" --music-dir "C:\Users\fiso64\Music" --username "fakename" --password "fakepass" --skip-existing --pref-format "flac" --spotify-id "12894214" --spotify-secret "2094234823"
```
As of right now you must provide an id and secret when using spotify (which you can get here https://developer.spotify.com/dashboard/applications, under "Create an app"). The throwaway I made was immediately disabled after I pushed to github.

## Notes:
- The console output tends to break after a while
- Much of the code was written by ChatGPT
