Fix #157: Can now import and play flac files
If you ever need an empty flac file with metadata again:
- Get a flac file (like https://archive.org/download/NineInchNailsTheSlip24bit96khz/01999999.flac)
- Tag it with Musicbrainz Picard
- Truncate it, keeping only tags with
ffmpeg -i in.flac -ss 0 -to 0.001 out.flac
Thanks @HgO for the trick!
