Listened to many a song for a while now and nearly all of them will clip when the music swells or crescendos. Turning down the player or phone volume doesn't remove it. It's happening at the re-sampling level.
I've also noticed playback will just stop randomly. I know DPS is quite a cpu hog (all for good, no worries) so I always quit all my other apps. Still the random stopping of playback happens more than I'd like.
