You can use iTunes to create your own personal digital music library and easily organize and listen to your collection of digital music files. You can also create your own custom audio CDs and transfer your music to an Apple iPod. If you are installing iTunes for use with an iPod, after installing iTunes, use the cable that came with your iPod to connect your iPod to your computer.
In addition, with iTunes 4.9, you can now browse and subscribe to podcasts from within the iTunes Music Store. Podcasts are frequently updated radio-style shows downloadable over the Internet. You can also transfer podcasts to iPod, for listening on the go. Pretty cool.
