You are the winner! Thank you for everyone who contributed suggestions, but, in the end, www.clipconverter.cc was, by far the simplest to use:

1. Open the URL
   
2. Enter the YouTube link in full (didn't work for www.tubechop.com)
   
3. Enter the excerpt time wanted.
   
4. Download into an MP3 file.

No additional software to download. No freeware containing adware viruses. No frustrations of multiple file manipulations and removing junk from your computer.

Please Freepmail me if you want the donation to go in any other name than Theoria. Otherwise, it will go to JimRob within the next 72 hours.
