Apple really needs to look at their software QA processes. Ever since I upgraded to 4.2.1, when I advance to next track, songs randomly start several seconds in. Sometimes even halfway through the track. And no, I do not have "remember position" enabled on any of them. And yes, I realize this is software and bugs are to be expected but this is a basic device function-to play songs correctly. Apparently this is a known issue as there are a few threads about it on the Apple Support forums but I can't believe that Apple fails to check to make sure basic things like this work before releasing golden code.
