When I first downloaded MixxZing it said it had a lockscreen widget included as well as a bunch of other features I never got around to playing with.
I thought the lockscreen widget was pretty cool and something the stockplayer was missing that my old Dare had. It worked a couple times but now it says I have to pay for the app to use that widget. wtf? Without it, MixxZing doesn't seem that different from the stockplayer, aside from playing videos.
