Audio in AE templates

Hi Folks, I'm new here. I'd like to ask which are the rules about the audio in the AE templates.
Let's say I'm selling a template but the audio is bought on a different stock web site. Is it ok to publish the clip with the audio in the preview section of the project?

Thanks

Hi Martin, for uniformity we would prefer if you use audio from Pond5 instead. Besides Pond5 audio makes AE templates look even more awesome.
