Bash: iterating directories for mp3gain

I'm still completely new to Bash. I'm looking to pass all the files under one given directory to mp3gain, but I want to scan them in sets of albums to use with the album tag -a, so I need a way to iterate over the individual sucdirectories, then perform mp3gain -a *.mp3 on each album folder individually, separate from the other subdirectories.

The directory is set up in the format:

~/music/artist/album/song.mp3

Could somebody point me in the right direction?

find $HOME/music/artist -maxdepth 1 -type d | while read dir; do
  mp3gain -a "$dir/"*.mp3
done

#!/bin/bash

for artist in *; do
    echo "$artist"
    if [ -d "$artist" ]; then

        cd "$artist"
        for album in *; do
            if [ -d "$album" ]; then
                mp3gain -a -k -d 2.0 "$album"/*;
            fi
        done

        cd ..
    fi
done
