how do i create a playlist i used to know how but i forgot ... i swore it used to be right click and add to playlist but thats gone now ... anyways ... someone help

It's quite simple. Click on the song that you want to put into the playlist(if you are selecting more then one song, hold the CTRL key as you click on the songs) then click on the 'Enqueue' button.
