Not so long ago music production was the playground of the minted. Without access to expensive equipment, studio time, engineers, manufacturing, and distribution there was no track. Now tracks can be released for less than the price of a Big Mac, but that doesnt mean they should.
How much are you willing to invest in your piece of music? If an artist is not willing to stake a few green queens on getting their track heard by the masses then maybe they shouldn’t.
When an artist (or the label investing in them) spends on decent promotion, decent artwork, or even pressing some promos to vinyl, they are making a statement:
“This music is worth something. This music is worth playing and worth buying”
Surely that is a statement all artists should be making.
Edit: I just wanted to add that this is different to investing thousands in a marketing campaign. That is more a method to reach masses of people and to make the music seem popular – something that is becoming necessary because of the volume of weekly music releases. This is more about giving music value again, and that maybe labels and artists would be more discriminating when releasing tracks if they had a significant overhead.
