I'm looking for interesting Audio Mp3 files to listen to on my mp3 player
For example:
Lectures (interesting knowledge topics.)
Great speeches by opinion leaders.
How to topics.
Insperational speeches.
Intellectual content.

Please point me in the right direction. Been doing some goole searches but sorting through is tedious.
Any help greatly appreciated
Thanks
RoR
