Great information again, very enlightening, thank you. I'm going to copy these two posts and study them like a "manual".
What I found in this Musformation thing is a guy who gives you a methodology you can stick to, a strategy... which doesn't involve buying his shiny new e-course for $59.95. In fact he also debunks things like buying FB ads or playlist listens, as crap. I also like this idea of staying several weeks around the same song: both as a way of "hammering" the song into people's volatile attention span... and also as an unsaid statement that your music is important. Not only for them, also for yourself; if I find one of my songs is only meh, I'll find very hard to promote it with conviction, make lyric videos, video clips, create buzz around it... I can connect this way of doing things to my craft, it's not only marketing strategy.
But of course the guy will probably be partial and for sure self-serving in everything he says. To say it all, I find him and his delivery so cringy that I don't even watch the videos anymore, I just read the transcripts . But I think the content is good, at least it's plausible, he has a consistent message from one video to another.
I never thought of internet marketing, when it comes to music, as "niche". To be honest, hearing it denominated like that is a relief for me, as it means there is life outside this big "computer god" who seems to have swallowed all the music creation and distribution in our days... I hope to growingly learn more about those other avenues...
