It´s really great to see so many $29 tracks are doing well in the popular list as well as new featured tracks. I know we are still early in the ADP world, but it looks very promising.
It would be really interesting if Envato could do a simple customer survey about what most customers are willing to spend on a great track budget wise. We already know now that customers easily spend $29 on a track, but how many falls off at $59 or $99 for example (standard license). A similar survey about sound effects would also be interesting.
Here is a very interesting article about pricing psychology: https://www.helpscout.net/blog/pricing-strategies/
