Yes and no. From the product page:
While these songs are listed as pay-what-you-want, if you do plan on making money off your game (either through ads, microtransactions, or direct sales), please subscribe to my Patreon. $1 a month can get you instant access to over 250 other songs you can use in your projects.

I understand that not everyone has access to PayPal, or Patreon, and I don't want to limit people's work because they are unable to support me. But if you have the means to toss a bit back my way, it's definitely appreciated, plus you get access to a ton of new music! :)
