i only saw the sense music player...and it looked more like an IPod where you can flick albums from side to side.
I didn't know that doubletwist had an app. I dl'd their PC program....and it sucks!!!! i don't even have 1 gig of music on my pc and it took over an hour to sync the music onto my droid x. then, once synced, the files were a mess, nothing was organized. most of the music was listed as "unknown artist." hardly an album art was there, etc. needless to say, i am not too impressed with doubletwist.
I then bought Isyncr. Great program! does everything you need it to for syncing your music from your pc.
I also bought the Pure music Widget, and it's okay. Doesn't really pop out at you , but it works. I was just looking for a visual stunning music player for my Droid X, and was thinking the sense player on the DInc looked nice.
