If you had a song to release today and no following how would you market/release it to ensure it reaches the most potential

 

I suppose that you mean "no followers" ?

 

yes!

 

3 Strategies
(1. Zero Money Zero Time ) (The Topics are just simplified and idealized to make the concept better understandable)

YouTube Shorts

Cut your song in 3-4 parts some Visualization and that's it

Best Chances to make a few thousands clicks with nearly nothing afford

(2.Zero Time , Some Money )
A simple multilevel social Media account setup to build up a hype before your release , can help a lot
(So accounts for Twitter, Reddit , TikTok, YouTube, Facebook, and what ever social media you can find before you release with some random Video, and other Posts )
In this context

(3.Some Time , Zero Money )
peddle it just everywhere, to every big guy in the business
:
Hey I have this "sweet ass fucking super cool"(only term to promote it the right way with exaggerations) song play it pleases and make me famous
(Chances are high that after a few hundreds or thousand tries, someone will play it and everyone will love it )

But to be true the market is very oversaturated and chances that this will work are just small.

 

If you're willing to spend some money, you could try running Facebook/Instagram & Youtube ad campaigns and target people who have shown interest in music that's similar to your style/genre.

 

make some madshit/funny/disturbing (depending on genre) music video so it goes viral on social networks,
if the music will be good, people will notice that and will want more

 

say one of the downloadable copies contains a code that'll trigger a notification for winning a $25,000 prize? of course there is no code or prize, but who'll ever know that
