Are ANY Keywords Actually Approved??

I sign up for the search marketing program, and in one week's time, damn near every keyword has been rejected.

Here is an example:
ipods
mp3

Both of them rejected for an affiliate landing page.
podmaxx.com

Reason being, there is not sufficient content on the page that is related to the keywords.

Am I looking at something different here??

 

i could see them rejecting it on the basis of trademarks. iPod is trademarked, i don't know if mp3 is, though. But for content? Hmm.
