If you have a high speed connection and a CD burner, you can opt to purchase a MP3 download and create your own CD using any one of several types of free MP3 software (such as iTunes or Windows Media). If you have the necessary connection and hardware then you can choose to burn your own Fitter U CD in the case of not having an MP3 player.
Don’t worry it is very easy to do.
However, if you have an MP3 player, then there’s no need to burn any CDs. Simply upload the MP3 files right onto your MP3 player from its respective software program (eg. Apple’s iPod uses iTunes to upload songs).
