Instrumental music sells best if you tie it into a purpose.
Massage music sells very well.
Yoga music sells very well.
Instrumental Christmas music sells very well.
Notice they’re selling more than just the music itself. They’re selling something that non-music people find useful. They solve a problem.
Imagine two candlemakers.
One says, “My candles have only the finest wax with the best quality wick!”
The other says, “These are prayer candles. Light one whenever you pray.”
There are dozens of people who will buy the first.
But there are millions who will buy the second.
