Apple has committed to making cloud storage and remote access to content the foundation of the new generation of both mobile and computing devices. The idea is going to be that our media library will be singular and accessible from any appropriate device, though this is happening in different capacities from different services. One of the most involved of these is the new iTunes Match, and this allows your music library from any device that is either running the iOS 5.0.1 or iTunes 10.5.1, or any later incarnation of each. Though iTunes Match does have a yearly subscription fee of $24.99, there is a growing area of consumers for which this price is paltry when compared to the service they receive. Here is a look at how to set up the iTunes Match subscription.
The first thing you need to ensure is that your computer is matching the correct requirements. If you are running a PC then you have to be using at least Windows vista, and for Apple computers you need the Mac OS X v10.6.8 or later. Your iTunes must obviously be at 10.5.1 and your iOS device at 5.0.1 or later as well.
To subscribe to iTunes Match you have to begin from iTunes, you cannot do it from your iPhone. Go to Store in the upper task bar and then select Turn On iTunes Match, which is right above Turn On Genius.
A screen will come up in the middle of your iTunes display that will give you a little extra information about iTunes Match, such as you can listen to music at 356 Kbps DRM-Free, and a button that says Subscribe for $24.99 Per Year. You will need to sign in with your Apple ID, which is the same one you use for the iTunes Store. Your billing info will likely be brought up for verification, though this may be implicit when you are signed in to iTunes. You will be asked to choose Subscribe again and then the process will be complete.
From this point you will be given the Terms and Conditions and iTunes will scan through the content available on your Library so that it can find matches in the digital database. If songs are not found then it may upload them, creating a digital registry for all of your musical content.
