Upper case in audio playlist?

Hello, I've tweaked audio_playlist module (e.g. http://www.victoryingrace.org/playlist/browse/audio) - and need to allow upper case in titles. By default playlist is all lower case. Would really appreciate help on allowing this possibility. I found some kind of function that's called - is that the right thing to remove from code to get Upper case?

I also need to put some text below header, and can't seem to figure out how to do it. I changed the header but can't add regular text below it.

Thanks in Advance.
