After many years of mediocre 30 second song previews, Apple now allows artists to upload 90 second previews.  Two restrictions apply: for the preview length increase the song must be 2 minutes and 30 seconds or longer, and lengthier previews only exist in the U.S. iTunes Store (for now).  The preview extension is very handy; purchasing decisions become easier when you have more time to demo a track.  Open up iTunes, head to the Store, and see if your favorite artists are embracing the positive change.
