trouble with sound

nevermind, this apparently does what I want it to:

ChangeDir "c:\program files\blitzplus\derek\quadblox"
Graphics 640, 480, 32, 2
heh = PlayMusic("music1.mp3", 2)
While Not(KeyHit(1))
If KeyHit(57) Then ResumeChannel heh
If KeyHit(54) Then PauseChannel heh
Wend
End

sorry, but making these posts motivates me to figure these things out. haha
