My guess is that the lack of album information is pretty common on disc players. The feature would be a cinch to provide, but I guess its asking too much. I purchased an LG Bluray model a couple of years ago that includes a built-in harddrive and CD information feature (gracie note), but the player cost over $200. I don't know whether that's a standard feature on the LG's.
If you decide to try streaming, your Panasonic won't stream Apple lossless files. It looks as if mp3 is your only option, if you're using Apple computers. PC users can also use wma (Windows Media Audio). The Panny does act as a DLNA renderer. I checked the user manual. As a rendering component, a smart phone or computer app can be used (media controller) to send files to the Player. The importance and benefit of the feature is that the controller devices sending the files will have a better feature set and graphical display than that offered by the Panasonic. For example, album art and playlists will be available. If this setup works well, it might be a blessing.
If you want to play uncompressed music files, then you'll probably want to look for something other than a BR player for the chore, and possibly need Ethernet connections to avoid dropped connections.
