Can I use CC BY-NC licenced music in my freemium mobile game?
<p>According to creativecommons.org, a CC BY-NC license stands for a Creative Commons license that prohibits you to use the material in "Commercial Purposes"  and for the commercial purposes they have defined it in this way:  </p>

<blockquote>
  <p>A commercial use is one <strong>primarily</strong> intended for commercial advantage or monetary compensation</p>
</blockquote>

<p>As freemium games (especially mine) can be played without spending even a penny and the in-app purchases are only meant to accelerate the process (so is not primarily intended for commercial I think?), is this game still intended as a commercial project with the definition given above?<br>
And should I ignore using such music?</p>

<p>If they receive a benefit (e.g. ‘better’ gameplay) in return for their payment it’s commercial.</p>

<p>If the payment is a pure gift (e.g. “I worked hard on this game, if you like it sling me a few bucks”) then it isn’t.</p>
