dikkiedirk is referring to the lack of network support within UAPP.
It would be lovely for those of us who have phones with limited on board storage. Or who would simply like to carry TB's of lossless music about (streamed via wi-fi from a external hard drive using a RavPower FileHub or similar). Only solution (as yet untested) that I can see to this issue with UAPP (at present) would be to rip music (or merge existing tracks) to a single album length file...
Fine for those of us that haven't yet starting ripping a vast library of CD's to lossless (uh, as in myself), were there the time allowed to do so.
Do I recall somebody saying that Neutron (or another player) supports streaming albums/playlists over a network/Wi-Fi ? Don't much matter to me if it doesn't support hi-res, plain old 44.1/16 will do the job.
I stream using gizmo/jriver and it sounds great. I have yet to configure it so that I can use it outside of the house, but it doesn't sound too hard to do.
