How to help independent musicians.
Engage posts
Like, comment, subscribe - Point the algorithm beast in the right direction! Even just pausing on a post tells the tech-overlords that you showed interest. Go the extra step, silence your inner grinch - click that like button! Maybe even drop a comment.
Rate/review tracks and albums
Most platforms have a rating or review system. Give tracks and albums a review! iTunes, Spotify, Apple Music, Amazon etc all have ways of providing feedback. More feedback tells the algorithm to serve this content to more of the masses.
Click the share button
Sure, you could actually share their music. But why sully your pristine collection of Puppuccino art with a post about someone's music? Even just clicking on the share button on many platforms will tell the datalords that someone wanted to share this music.
Add the music to playlists
Even if you don't listen, having the track added to a playlist can help.
Got a work playlist? restaurant? store? add it there.
Tag the gatekeepers
Like a song? Post about it and tag media outlets, reviewers, journalists, influencers, editors, magicians etc
Its the world we live in, might as well inject some merit.
Direct sales
If you are going to buy the music *GASP*, buy it through BandCamp or directly from artist.
