I've tried quite a few of these, Poweramp and Neutron seem best sound-wise, but I agree that they're fiddly. I currently have Neutron on my Razr Maxx, find it really difficult to manage, difficult UI. Probably going to uninstall it and go back to one of the many players I've used, maybe Poweramp again (have tried Meridian, Winamp (buggy), Doubletwist, Mixzing, and some more of the usual suspects). I've decided I don't really love using my phone as my music player, anyway. I often plug into a pair of speakers at work, have to leave it and not receive calls to do that. Also calls interrupt the flow of the players. I do subscribe to Mog, which has much flexibility and can be used on phone, computer, iPad, etc. Also some streaming apps to listen to music from my PC. Generally, I just prefer a dedicated digital audio player, and use my ipad, ipod touch, and HiSound Audio Studio V player for listining that is more than casual, but not at the main stereo.
