```
- Provide either track-col & artist-col (ideally), or full-title-col in case separate artist and title names are unavailable (useful when downloading a csv of a YT playlist). 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
- Files satisfying `pref` conditions will be preferred. Files not satisfying `nec` conditions will not be downloaded.  

Example use (with a csv from https://exportify.net/):
```
slsk-batchdl.exe --output "C:\Users\fiso64\Music\Playlists\test" --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"
```

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