Even if you bought an exceptional Michael Kelly guitar at Musicians Friend and made the best album in the world there's no guarantee that the Wider Music World will notice you. I've just been watching a programme on Choice TV which pointed out that some musicians who have music on Spotify have to have up to 125 downloads of one of their tracks before they earn as much as a dollar. It isn't Spotify that's causing this issue, it's the fact that there are an awful lot of musos out there, and they're all chasing your money. Social media is a good way to improve your chances of being heard (as one of the women musicians interviewed discussed), but it takes a fair amount of promotion all the same, and most of that's going to have to be done by you, otherwise that one dollar you've earned will be eaten up by some expensive advertising campaign. And that takes away from your productive music time.
I was talking to one of the older ladies at church (older than me, that is) this morning, and she was telling me about her artist son (he's now in his sixties), and how it's never been easy for him to promote himself. He's had exhibitions and his name is known but that kind of promotion is hard work for him, as it is for many artists. Most artists - musicians, painters, writers etc - need a patron to survive well enough to be able to do their best work. The reality is of course that most musicians, painters, writers etc don't have patrons, and struggle. They have to deal with daily life, real life, and that's another factor that affects their work.
This is a bit of a minor rant, really.
