There's a reason why your SoundCloud may still only have 500 followers after you being on there for a year. It's because you're not focused and you haven't taken any time to implement any strategies from people who are doing better than you in music right now.
Notice how I said BOOKS and not just BLOG ARTICLES. Articles are nice to read, but there is always (and I repeat, always) more valuable information when you pay for it.
I know some artists just can't get over that hump of paying for books or courses to help with their marketing, but those same people are usually stuck in an endless rut trying to make more money with their music.
In fact. Here's a list of things 'aspiring' artists generally spend more money on than they do their music career:
1. Overpriced sneakers/clothes
4. Paying for the bar/club
5. Video games
6. That thing on Amazon you just 'had to have'
My point. If you find it's easier for you to spend $20 at the bar or T.G.I.Friday's than it is for music promotion or a good marketing book... Re-evaluate your goals.
