Wait to Check for Double Click

[arig]

Hi there,
I need a macro that will wait to check if my mouse button is clicked twice before skipping a song. Kevin sent me this code a while ago, but I've still been having some issues with it. 

Macro Left Click - Play
Trigger #L //FF_Mouse1     

Code:

wait 0.4 ML; err int singleClick=1
if singleClick=1
,key (VK_MEDIA_PLAY_PAUSE)

This goes along with a 2nd macro, seen here.

Macro Left Click Double - Spotify Volume Mode
Trigger ##L //FF_Mouse1     

Code:

Copy      Help

if win("" "AutoHotkey")
,clo win("" "AutoHotkey")
,OsdHide
else
,run "$user profile$\Downloads\Spotify.ahk-master\Example Hotkeys.ahk" "" "" "*" 0x10000
,_monitor=1
,OnScreenDisplay "Spotify Volume Mode" -1 +1 +1 "Calibri" 48 0xFFFFFF 1 "" 1

The 2nd macro has been activating when I try to activate the first one. If I try to press the buttons too quick, both macros will activate. Does anyone have any idea how to improve this? It's not the worst thing ever, but it's getting very annoying.
Thank you
