I made a few simple changes in the list view's code and it resulted in much smoother scrolling. AVRCP 1.3 should be fixed on devices that support it now. This fix broadcasts some new intents which might cause duplicate scrobbles if you have the simple last.fm scrobbler setting enabled, so I reset this value. In simple last.fm scrobbler, the tracks you play should show up under the default "Android Player"
