The digital age is both a blessing and a curse for modern-day musicians. Websites like YouTube and Kickstarter can equal big business for artists, as online campaigns allow them to reach out to their fans directly via socia networking and potentially become viral sensations overnight.
On the other hand, free music streaming sites like Spotify and Pandora provide little financial yield for the musicians themselves ($0.004 per play if you're unsigned) and cannot be relied upon to cover the ever-mounting costs of travel, instruments and gear, recording sessions and software, album distribution and any additional publicity required to become a household name.
Also, it should be noted that unless you're playing sold-out ampitheatres á la Paul McCartney and Justin Bieber, ticket sales won't net you a fortune either.
Lots of musicians get a jumpstart due to wealth or family connections, like when Taylor Swift's investment broker father spent millions of dollars to finance her first album in 2006 and when Lana Del Rey's millionare parents bought her out of one contract to sign her with another more lucrative label for instant stardom in 2011.
Does it depress you that Kelly Osbourne (daughter of Ozzy) got a record deal to sing horrible Madonna covers, while scores of other truly talented bands and artists have dwindled into obscurity? Unfortunately, this kind of gross nepotism runs rampant in the music business today (see Jann Wenner putting his 22-year-old son in charge of RollingStone.com) and in most other areas of the entertainment industry as well.
So, how do artists make money when they don't already have the money to spend?
Many relatively well-known musicians still keep their day jobs; not surprising, considering that the average musician makes only $34,000 off their music in America each year before deducting expenses from touring, recording, etc. (which, given the rising prices of gas and fancy recording software, can wrack up quite the bill).
Even Pitchfork-famous indie artists like Grizzly Bear and Cat Power have struggled to make ends meet; so be practical about the pros and cons of a musician's lifestyle before committing to it full-time.
If you're only making music for the money, then you should get out now. But if you truly love what you do—and don't mind riding in a smelly tour bus, starting out in tiny venues and living off Ramen noodles for months (or years) until you get your big break—then ignore the haters and keep rockin' on.
