Good, but a little challenging if you don't have the time to sit and play for ages. Sort of deceptive, in that all the songs have very easy intros, but then move into impossible chords. By that I mean five-note chords, that are impossibly spaced (coming form one who can only just about span an octave at the best of times).
The melody lines are provided (both music and lyrics), with the character names as well, which makes it easier to imagine whilst playing, which is good.
Also the words are the American version, though it makes little difference to the playing :)
