Change specific text in audio module

I'm using the audio module to manage my church's podcast on our site. I've used the string overrides module in order to replace "artist" with "speaker" and "album" with "series" when looking at an individual sermons page. For some reason though it doesn't seem to work for the page title when browsing the podcasts by "album". For example, if you look at this site you'll see how it says "speaker" and "series" in the audio info near the top.

However, if you click on the series link to view all the other sermons from that series, the page title still uses the term "album". Anyone have any idea what I can do to change that so it says "speaker"? Not sure if there's a way to make string overrides work, or if I can go into some file in the audio module folder and change something to replace it.

Any help would be greatly appreciated.

Thanks!
