If you are in England go to your local library (or buy it from a bookshop) and get out a book such as "MP3 for Dummies" or similar. In there you will find a version of MusicMatch Jukebox which will let you do what you want (as well as lots of other stuff)

If not try here and you should be able to download it - Music Match 6 - it is not the latest version but should be more than adequate for what you are trying to do
