Is there any free software that can record only partial of the song (audio file)?

I would like have only partial of a song (audio file), eg chores only. Any free software that I can play the song and record part of the song i want? In window there is a sound recorder but that one need to be a wav file. Mine is either a audio (fr CD) or Mp3 file. May I know can this be done?

Thanks

'Audacity' is an audio editor.
You can import and export parts or all of an audio file.
If you wish to export mp3 files, click 'Edit' > 'Preferences' > 'Libraries' and download the Lame MP3 library.
