Are we allowed to use audio from the internet if we have the license for it?
i'm not entirely sure, but i would say no. my reasoning is that the license rule really only applies for fonts, as cited:
You can use fonts from the internet, as long as you have the correct license for it.
i would personally say that audio falls into more of an asset category since
a) it was likely created before the jam
b) as it is not a generator, you don't have any control over the output.
