Music works best as art, though if your goal is loads of money and fame, there are roads leading to this destination as well. To get there though requires a great deal of discipline and manipulation, and a great deal is at risk. After all, you might end up another Lady Gaga. How much is your soul worth?
To be in? Haha, yeah. Extremely good. If you can be in them both, superb. The only more financially beneficial industries I think would be the drug trafficking industry or the slave trade industry, or something, and they don't always bring job satisfaction, hahaha.
