When you want to download music for your iPod, or if you just want to download some of the thousands of songs available in iTunes, you need to download an application to convert it to other formats. However, most applications are expensive, and most applications aren't free. You can use a free software program that converts audio files into other formats. These free programs are available online.
The first step is to get the audio files. There are many sites that will host them. Some sites will charge a fee for each conversion, but all you have to do is pay a small one time fee and then you will have unlimited access to all of their websites. Once you have these files, you can check out the online versions of a lot of free applications to determine which one you like best. One of the free applications is called iTunes. Once you download the application, you need to install it and open it up.
You can find instructions on how to use this application on its website. When you are downloading the audio, iTunes will have a folder where you can sort the audio files by artist, title, etc. The first time you use this application, you will need to scan through the audio file to see if it is already compatible with iTunes. Many audio files will not be compatible with iTunes, so you will need to download the latest version of iTunes and convert it to iTunes format. However, there are applications that will convert your files automatically for you, so that's why you should download an application that is free.
