i Tunes Match non-active
iPhone 6, iOS 8.4.1
Howdy erhancoskun,
Thanks for using the Apple Support Communities.
I see from your post that you would like to know how to enable iTunes Match on your computer. iTunes Match is now a part of the iCloud Music Library.
To enable iTunes Match:
For Windows:
Once it's enabled, go to File > Library > Update iCloud Music Library to refresh iTunes Match.
For more information, see iCloud Music Library: Understanding differences between Apple Music and iTunes Match.
Take care.
