I was lucky enough to have spent a few years singing in an awesome metal band. We got a record deal with Unique Leader, who is one of the most significant labels for the style we played. I got to see my album online, in stores, and most importantly, in peoples HANDS. It was pretty fulfilling.
I also got to meet and play with a lot of other bands, who had also signed record deals. Some with bigger labels, some smaller. Some had endorsements, vans, busses, etc... No matter though, they all got what they had the same way: Touring. And the reality is that even the best bands, and the really successful ones, didn't make much money. And it's NOT as glorious as one may think. Hotel rooms and limos went out in the 80's. Nowadays, you're far more likely to be spooning with the bassist in the back of a van while the drummer is driving to the next gig.
I'm not arguing for or against music as a profession. It has wonderful rewards, and it has it's shortfalls. However, I'll be brutally honest with you: To become and stay successful as a recording artist can and most likely will require lots of touring. And even then, success is not guaranteed. In addition, you're not going to make a lot of money. I'm not going to drop names, since finances are private matters, but I'll give you a good example: From near where I am, there is a very successful band. They get regular MTV play, have an awesome recording contract with a major label that is one of the biggest and most long standing in the industry, and do massive tours and festivals all year long. I had always assumed that these guys were making HUGE money. Once, when setting up a bill, I found out that it cost upward of $10,000 to play a single show. Figure that multiplied by 5-6 shows a night, 8 or 9 months at a time, and I just assumed these guys were all loaded. Turns out, in fact, that when touring each band member gets around 20-30 dollars a day to live off of. That's it. Any other money that make is off merch sales, and that goes into a band-fund. In other words, it's less than they'd be making working at McDonalds. In ADDITION, when they are off-tour, the label pays them around $800 a week each to live off of. This is again the equivalent of working at McDonald's, only as a manager this time.
It's not glorious, and it's not the most intelligent way to earn a living, but it has immense rewards especially if you're doing it because you love to play. If you are simply entertaining the idea of lottery winning style pay and rock stardom, though, I'd drop the idea pretty quickly.
