This song (along with Black Sabbath's other classic, "Iron Man", in Guitar Hero) was shortened significantly for its injection into the Guitar Hero culture. The playing level on any mode is not very difficult for someone who's made it this far into the game but the guitar solos in the middle and towards the end can easily cause a player a frustrated fail. Repeated practice is recommended for these sections if they prove too difficult but Star Power can easily push you through the hardest parts in both made up of fast alternating yellow, red and blue notes. These sections, however, only last a brief time, roughly 10 to 15 seconds so Star Power can keep you from failing this harder but still very fun song.
