setMetadata.sh

#!/bin/bash
# setMetadata
#
# extracts metadata from MrSuicideSheeps videos, combines them with the Audio files and sorts them into the output folder
# This works because his Videos always have a title in the form of "Interpret - Title"
# install atomicparsley-largefile from AUR in Arch Linux
# depends: bash, AtomicParsley, sed
# problems: AtomicParsley limits comment length to 256 characters, removing part of the description; so write it into lyrics also
