Applescript help

Is someone able to make this code work for any media playing, not just spotify? (Netflix, youtube, apple music, etc)

set haserror to false

tell application "BetterTouchTool"
	if is_app_running "Spotify" then
		try
			tell application "Spotify"
				try
					--GET NAME AND ARTIST
					set sName to (get name of current track)
					set sArtist to (get artist of current track)
					
					if sArtist is not "" then
						set nowPlaying to sName & "  —  " & sArtist
					else
						set nowPlaying to sName
					end if
					
					--GET ARTWORK
					set artworkURL to artwork url of current track
					
					--save artwork
					set fileName to ((((path to application support folder from user domain) as text) & "BetterTouchTool:" as text) & "spotify_cover.png")
					
					do shell script "curl " & artworkURL & " -o ~/Library/Application\\ Support/BetterTouchTool/spotify_cover.png"
					
					
										--FIX JSON BREAKING STUFF----------------
					set THESUBJECT to nowPlaying
					
					--escape "\" via find replace to "\"			
					set prevTIDs to text item delimiters of AppleScript
					set text item delimiters of AppleScript to "\\"
					set subject to text items of THESUBJECT
					
					set text item delimiters of AppleScript to "\"
					set THESUBJECT to subject as text
					set text item delimiters of AppleScript to prevTIDs
					
					-- Escape nasty JSON-breaking double quotes
					set aString to THESUBJECT
					set astid to AppleScript's text item delimiters
					set AppleScript's text item delimiters to quote
					set aString to text items of aString
					set AppleScript's text item delimiters to "\\" & quote
					set aString to aString as text
					set AppleScript's text item delimiters to astid
					-- Quotes have been vanquished
					set THESUBJECT to aString
					
					--output
					set nowPlaying to THESUBJECT
					--FIXED JSON BREAKING STUFF----------------
