Automatically remove all music from mp3 talk show

Is there a tool that can automatically remove the music sections of a given mp3 file so only the talking part is left? This would create a better listening experience when listening to the file on my portable mp3 player.

Currently I'm doing the task manually by looking for 'dense' regions using Audacity, but this is very cumbersome for large files.

Any help would be appreciated.

Edit: I found a podcast version of the radio show without music, so I don't need the tool anymore. Thanks to all who provides answeres.

I don't believe there's an automatic way of achieving what you're looking for but I think you need to experiment with the High Pass and Low Pass Filters to extract the voice part of your mp3.

Even then that would probably extract the vocals (if there are any) from the music part.
