I subscribe to a lot of magazines, because I'm old school. Unfortunately for magazine publishers, not everybody is like me. In fact, most people aren't like me.
So what's the solution? Increase your subscriber base by getting the people who buy (in other words, the biggest fans) to give away free subscriptions in hope of winning other people over.
Example is below...
It works for big magazine publishers and it will work for you. CDs are cheap, so you could do the exact same deal on your music. $10 for a CD, plus two additional CDs for the buyer to give to friends.
Look, people who want to share your music have nothing to stop them from making copies, so you might as well give those people the "official" version of what you do and encourage word-of mouth around it.
Or try this technique with tickets to your next gig... The more people in the audience, the more likely those people will have a good time. And it's more opportunities for you to win over new fans.
