Hello!
I am a novice beatmaker from Russia. Not so long ago, I began to master this skill
I am here to meet and learn more about musical tips and tricks.
I want to ask the pros for advice: what services do you use to promote your tracks?
Soon I plan to finish the first track and I can not decide what to do with it further.

There are plenty of professional musicians who are not pop stars, but there are no professional hip-hopsters who are not pop stars, and I'd be willing to bet there are precisely no pop stars of any kind answering questions in this forum nor will there ever be. If there were a recipe for becoming a pop star, we'd all be pop stars, except in that case none of us would be pop stars because the whole premise of pop-starring is that the size of the audience hugely outnumbers the number of stars. If for some bizarre reason you actually enjoy "beat-making", do whatever the hell you want with it, just don't expect any significant remuneration of notoriety.

By the way, the idea that you are seeking to "promote" your work without having finished even a single "track" is absurd. You aren't entitled to success at any kind of endeavor until you've acquired some experience at it. Make fifty tracks, over a period of at least five years or so, and then ask. (Unfortunately, if the endeavor is still "beatmaking", my answer will still be as in my first posting in this thread.)

Hello!
Himself recently asked this question. You can, of course, do everything yourself - upload to streaming platforms, monitor everything. The same applies to post processing - mastering and mixing. But this is a huge waste of time.
There are a bunch of sites where all this can be done quickly and relatively inexpensively. I tried several services and so far I have stopped at theamadei.com. There are pros and cons, as elsewhere, but so far everything suits me.
Test different services, choose what is most convenient for you and use.
I wish you creative success
