将子文件夹名称添加到文件名，并将文件移动到当前目录

Question

I have a car stereo that reads USB sticks, but the stereo's "random" function only works on one folder, so I want to move all files to a parent folder, "STICK/music", but to have the Artist, and Album if any, added to the filename. But what I've done is sort of hard-coded, and I'd like to be able to use different sticks. I would like to have these ("RHYTHMBLUES" is the name of the stick):

/media/homer/RHYTHMBLUES/music/Artist/Album/name1.mp3
/media/homer/RHYTHMBLUES/music/Artist/Album/name2.mp3
/media/homer/RHYTHMBLUES/music/Artist/name3.mp3
/media/homer/RHYTHMBLUES/music/Artist/name4.mp3

renamed with folder names and moved to "music":

/media/homer/RHYTHMBLUES/music/Artist-Album-name1.mp3
/media/homer/RHYTHMBLUES/music/Artist-Album-name2.mp3
/media/homer/RHYTHMBLUES/music/Artist-name3.mp3
/media/homer/RHYTHMBLUES/music/Artist-name4.mp3

I thought of having a bash command to call "doit":

find . -type d -exec sh -c "cd \"{}\" ; /home/homer/doit \"{}\" " \;

and "doit" would contain:

#!/bin/sh -x
echo --------------------------------
pwd
for i in *.mp3
  do new=$(printf "${1}/${i}")
  # remove the ./ at the beginning of the name
  new=`echo "${new}" | cut -c 3-`
  # replace folder separators
  new=`echo "${new}" | tr '/' '-'`
  echo "$i" "/media/homer/RHYTHMBLUES/music/$new"
  mv -T "$i" "/media/homer/RHYTHMBLUES/music/$new"
done

doitbaby.sh

#!/bin/sh

moveTo () { # $1=directory, $2=path, $3=targetName
    local path="$(realpath "$1")"
    for file in "$path"/*; do
        if [ -d "$file" -a -n "$3" ]; then
            moveTo "$file" "$2" "$3""${file##*/}"-
        elif [ -d "$file" ]; then
            moveTo "$file" "$path" "${file##*/}"-
        elif [ -f "$file" -a "${file##*.}" = 'mp3' ]; then
            echo 'FROM: '"$file"
            echo 'TO  : '"$2"/"$3""${file##*/}"
            # mv "$file" "$2"/"$3""${file##*/}" # Uncomment this for real usage.
        fi
    done
}
removeEmptyDirs () {
    local path="$(realpath "$1")"
    for file in "$path"/*; do
        if [ -d "$file" ]; then
            rm -fR "$file"
        fi
    done
}
moveTo "$1"
# removeEmptyDirs "$1" # Uncomment this for real usage.

Note I have commented 2 lines in the above script. Test it first before any further real actions.

Call the script like this: (Make sure the path is correct. This is the expected path by this script by the way.)

./doitbaby.sh '/media/homer/RHYTHMBLUES/music/'
