For music I'd look at Venus.
Your Libra Venus conjunct your mercury and North node indicate musical talent. The mercury connection suggests that it's a well integrated part of your thought process and that you have aptitude analyzing and with reading and writing sheet music/composing. Your north node connection to venus shows music in general is a possible career.
Your mc conjunct jupiter shows that you posess inherent luck career wise.
Your moon/Neptune/Pluto conjunction shows a great amount of creative potential. This conjunction squares your Venus and north node which amplifies your natural creativity and musical talent. Venus/North node square your moon/pluto/neptune could mean that your intense emotions and potential escapist tendancies could interfere with your future success (a lot of musicians have drug problems for these same reasons: intense emotions, escapist tendancies), but if you don't let your emotions control you and stay grounded this can enhance your musical talent.
Planets squaring the nodes generally means there are karmic issues at play. Your 11th and 8th house are at odds with each each other, so you'll want to work on bringing balancing to those 2 houses in your life.
