Apple iPod event to focus on iTunes music discovery?

A large portion of tomorrow’s Apple special event will be spent discussing improvements to iTunes’ music discovery features, a new report suggests. Citing unnamed sources, Cnet reports that Apple will double the length of song previews from 30 to 60 seconds in a bid to encourage users to find songs via iTunes instead of using increasingly popular services such as Pandora or YouTube. The report also claims that Apple’s rumored cloud-based music service is unlikely to be announced at the event. Apple’s 2010 iPod/music event will begin tomorrow at 10:00 a.m. Pacific Time.
