Not very often, no. And even if I change it, it will always have something to do with Gowan یا Styx (well if it has something to do with Styx, it automatically has something to do with Gowan since he's their singer, keyboardist and stage entertainer xD). For example, right now, my جملہ معیاری consists in lyrics from the song City of the Angels سے طرف کی Gowan.
