Music Cancel

Why Cancel the Music? 
 Mega Man 3's soundtrack, while amazing, generates lag. By removing the background music, the game simply runs faster. 
 Technique 
 By taking a spike death on the exact same frame as a screen transition, the "Mega Man dying" sound also causes the background music to stop. 
 This can be done in 
 
 Doc Shadow (reliable) 
 Dos Spark (50/50 or 75/25) 
 
 Other locations nobody goes for it 
 
 End of Doc Gemini (no known setup, saves frames) 
 
 Other Music Cancel Locations 
 These use other one-off techniques of canceling music, at least partially for the same desired "no music = less lag" effect.
