I setup Pogoplug to have remote access to my large music collection on my iPhone without requiring to have my computer on constantly.  Access is working fine, but the iPhone app is brutal compared to other server/apps I had previously tried.  Having switched over from using Audiogalaxy, the lack of capability to play playlists or albums or even queue more than one file and the lack of complete file listing makes this app unusable for the purpose.  With the addition of upnp it seems a no brainer to set up a solid, elegent solution for streaming media to mobile devices, but the app side is failing significantly now.  Any suggestions for other iPhone apps with improved interfaces or alternate solutions?
