Music is what happens when creative people make sounds. There doesn't have to be only one monolithic "music market". Just because TV is using "digital musicians" has nothing to do with the four guys who play improvised music every Monday at Jerry's on Division Street, or the dubstep cats working their butts off to create prodigious amounts of recorded, disposable music or the guy who plays contrabass for the North Shore Symphony Orchestra.
So fucking what if the music on television is done using samples? And what the hell is "television" anyway? Isn't that what they used to call that big screen in the living room that I use to watch Netflix and streamed torrents?
Let's not panic. I've made a portion of my living with music since about 1980. Technology has changed since then. People still make music. In fact, I bet more people make music now than back then because the technology has democratized the production of music and made it easier to learn to play than ever.
If you're still looking to start a band and sign a deal with a major record label and..profit!, then you really need to do everyone a favor and sell your instruments and use the money to buy lottery tickets. If you're looking to have a career as a musician and pay the bills then the best approach is the same as it ever was...practice. There's nothing to indicate it's any harder today than it was when record labels and musicians' unions were king. That doesn't mean there's no need for record labels and musicians' unions, but if you don't panic and adapt everyone will be OK and there will still be music in the air and lots of lovin' everywhere so give me the night. Ooh oooh.
