We've heard rumors of longer iTunes song previews, but it looks like Apple is finally preparing to begin offering them. Soon you'll be able to enjoy a whoppin' 90 second preview of any song over 2.5 minutes in length.
Shorter songs will still have previews lasting only 30 seconds, but that's just something we'll have to live with.
We don't know when the longer song previews will roll out, but considering that Apple is informing music labels of the change right now, it shouldn't take too long. [MacRumors]
