Apple may at least double length of time users have to preview music tracks on iTunes, according to a CNET source.
Currently, iTunes offers 30-second snippets of songs, a feature designed to give users a taste of the music to help them decide whether they like it enough to buy. Some users have long complained that half a minute isn't enough time to really hear a song.
CNET also notes that it's unlikely that Apple will reveal iTunes Cloud services on Wednesday, given that they have not acquired permission from the labels to do so.
