I need an smb audio app thatll work in the background and is compatible woth multiple audio formats (mp3, ogg, aac, flac, wma, bonus pts for opus). recommendations? XBMC supports the formats I need, and works over SMB, but doesn't work in the background. Ditto eXPlayer. This app FileExplorer works but only for mp3 (the paid version supports more file formats for video but apparently not for audio). ideas?
