I have a Pi 2 Model B, running Kodi on OSMC with the Confluence skin. I have all my photos, music and videos stored on an external hard drive, formatted with NTFS, plugged directly into a USB port. The files are organised into folders by genre, artist, album, etc. In Kodi I can see all the folders on the external drive, navigate around them, and play all the media. The music files correctly display the metadata tags I have defined when I select them.
This setup all works fine. However, the whole user experience is akin to manually browsing the file system in Windows Explorer, and manually selecting files to play. I was expecting a media centre O/S to offer a user experience more like a media library, e.g. iTunes or Windows Media Player. It would be nice to have all media displayed in a flat list, with custom grouping/searching/sorting based on metadata, not physical folder structure.
Does Kodi support this type of user experience? I have gone through all the settings dialogs that I can find, but I can't see anything useful. There is a "library" checkbox in the view menu on each folder, but it's always disabled. Can anyone either (a) tell me how to achieve this on Kodi, or (b) recommend another O/S that does what I want?
