Two months ago, there were rumors that Apple would be doubling the length of song previews in iTunes, which would benefit users and potentially lead to more sales. Today, Apple announced that they would be tripling the length of the previews to 90 seconds, which is more than enough time to get a good feel for a song, and aid in your purchasing decision.

`We are pleased to let you know that we are preparing to increase the length of music previews from 30 seconds to 90 seconds on the iTunes Store in the United States. We believe that giving potential customers more time to listen to your music will lead to more purchases.`

The change should be happening “very soon”, and may coincide with iOS 4.2’s release. (You know Apple, they like to keep things tidy!) There’s no word on when (or if) the change will be made in other countries, but hopefully Apple is working on it.
