If you’re a frequent iTunes shopper, you’re no doubt familiar with the 30-second previews that you’re given for each song. 30 seconds is usually enough time to make up your mind about a track, but not always. Thankfully Apple has decided to roll out 90-second previews on certain songs which are over 2:30 in length. It might not be the most revolutionary change to the service, but still interesting to note since it seems to be the first music service to take this extra step.
