Applescript - Rickroll testing error

[Gravy59]

Hello. I am making an AppleScript + automator RickRoll Application. I have an afplay file to play 'never gonna give you up' (classic rickroll song) but to keep it playing over the inverting screen and hundreds of windows opening (option+cmd+w to close them all) I use 

afplay /Users/████/Documents/RICKROLLD.mp3 > /dev/null 2>&1 &

the > /dev/null 2>&1 & makes it IMPOSSIBLE to stop, so every time I test it I have to mute the volume otherwise face the terror of 'never gonna give you up' for the duration of the song. Is there a better way to do this?
