Is there a tool that will either
- let me run a script over files in a directory tree in parallel
- re-encode a directory tree of music files in parallel
while being robust about interruptions (don't have to restart if I interrupt it and run it again), etc.
I'd rather not write this even though it would be a good little exercise.
(I need to recompress my music collection, for my car's stereo, and it needs Very Particular metadata.)

in reply to Ben Zanin • • •@gnomon I'll need mp3 and was thinking of batching all tracks in an album, which kinda matches my laptop's number of cores.
I need to experiment a bit with the stereo first; it doesn't pick up the track number field, so if it just sorts an album's tracks in alphabetical order I'll need to tell ffmpeg or whatever to output track numbers as part of the track name.
(everything is in flac; I need mp3 smaller than the bitrate I used initially, or music won't fit in an USB stick)
