I happily plunked down $25 when iTunes Match was released last November. I loved the idea of accessing my iTunes music library from my iPhone and iPad. Since then, however, I ponied up for Spotify Premium, which I greatly prefer to iTunes Match. Between Spotify and Pandora, I rarely find myself firing up iTunes, and I can't remember the last time I used iTunes Match to tunnel into my iTunes library from my iPhone or iPad.
I suspected that my iTunes Match subscription would auto-renew after a year, and it turns out my suspicions were correct. If you do nothing, you'll drop another $25 for another year of iTunes Match. It's easy to turn off auto-renew for iTunes Match, if you know where to look.
To do so, launch iTunes and choose Store > Sign in (if you aren't already signed into your account).
Once you are signed in, choose Store > View My Account.
Next, scroll down to the iTunes in the Cloud section and click the gray Turn Off Auto-Renew button to the right of iTunes Match.
You'll know your command was received if the button reads Turn On Auto-Renew. Also, next to the iTunes Match header, it will read, "Your subscription will expire and your music in iCloud will no longer be available on [such and such a date].
