To add to the list DoubleTwist sync'd all of my music and presumably my playlists into the device memory. Problem is the Sense music player can't find the music and play it. Astro is no help either.
Alright, nevermind. If you're having trouble with this make sure the usb cable in unplugged. And secondly open the music app and go to playlists and let it load for awhile. Took me 5min for 800 songs on 4 playlists.
