It's a great way to both increase your SMV but ALSO to just find a way to expand your mind, have an interest to focus on and, in some cases, an highly marketable skill.

Focusing of music - if you like it - looks like having the highest possible reward ratio if you can keep yourself reasonably attractive (not even necessary if you get famous).

Just carrying a musical instrument has been studied to increase attraction on the short term - just at sight, without knowing if you can play it.
