Spotdl

Fixed
- Fix crash if YouTube search results contains live streams
([ritiek](https://github.com/ritiek) (#735)
- Skip invalid tracks returned on playlist endpoint with Spotify Web-API
([ritiek](https://github.com/ritiek)) (#732)

Fixed
- In some cases when using `-f` to create sub-directories from metadata, where the
full slugified download filename and the non-slugified download directory happen
to differ, the download would fail. The download directory will now be derived from
filename itself so that the sub-directory name always overlaps.

when `--list` is passed. ([ritiek](https://github.com/ritiek/spotify-downloader)) (#722)
- Failure on invoking spotdl if FFmpeg isn't found. It should now warn about missing
FFmpeg and move ahead without encoding. ([ritiek](https://github.com/ritiek))
