Its been a while since I updated the Applescripts for Spotify, it looks like Spotify now supports Applescript directly. So I present the new updated scripts here. Credit Aaron Lidman who first brought this to my attention.
Play Pause
tell application "System Events"
set MyList to (name of every process)
end tell
if (MyList contains "Spotify") is true then
tell application "Spotify" to playpause
end if
Next Track
tell application "System Events"
set MyList to (name of every process)
end tell
if (MyList contains "Spotify") is true then
tell application "Spotify" to next track
end if
Previous Track
tell application "System Events"
set MyList to (name of every process)
end tell
if (MyList contains "Spotify") is true then
tell application "Spotify" to previous track
