As I understand it the standard license covers up to 10.000 copies/ downloads. I found this passage in the FAQ which seems to answer your question.
Can I use music in an audio-only end product such as a podcast, audiobook, or guided meditation?
Yes, as long as the audio-only end product is larger in scope and different in nature than the music itself. As a rule of thumb, the music alone must not comprise the primary value of the end product, and should have speech overlayed and interspersed throughout. You can never distribute the music track as-is or with superficial modifications.
Example: You can use a relaxing music background to underscore your guided meditation voiceover recordings, and sell a CD of this to your spa customers
