You will have to pay for the premium version from Mp3 Youtube if you want to use multiple recordings. If you feel that MP3 downloading is too confusing, just consider sending it as an email attachment.
This small program allows you to record, copy and listen to MP3 files without leaving your computer screen. You will also have the option to record only what you want to use at the time you make the recording. Since it is a simple program, you will probably never need to take a portable MP3 player
