private Map < String, List < Song >>

 byArtist() {
  Map < String, List < Song >> byArtist = new HashMap < > ();
  for (Song song: mSongs) {
   List < Song > artistSongs = byArtist.get(song.getArtist());
   if (artistSongs == null) {
    artistSongs = new ArrayList < > ();
    byArtist.put(song.getArtist(), artistSongs);
   }
   artistSongs.add(song);
  }
  return byArtist;
 }
public Set < String > getArtist() {
 return byArtist().keySet();
}
public List < Song > getSongForArtist(String artistName) {
 return byArtist().get(artistName);
}

tomandrews there you go. google "java code formatter" if you need help cleaning up a post.

It's almost as quick as lol'ing, and about a thousand times more useful.
