2) When selecting a bunch of files (.mp3/.flac) and selecting Play in Media Center, they are sorted and played by 'Sequence' - how can I get them to play sorted by 'Track'?
Unfortunately, no media player gets this right. Understandably, they look at the situation from the viewpoint of always using their player, and therefore, from the viewpoint of using Music Libraries, rather than File Explorer.
Without other intervention, using the File Explorer loads the files in alphabetical order, which then plays Track 1 followed by Tracks 10, 11 and 12, followed by Tracks 2, 3 and so forth. And that's if you have the track number at the beginning of the filename, otherwise you get just alphabetically by track name.
So, in order to get it to sort by the Tag - "Track" - you have to import into the Music Library first. This causes problems if you want to audition the album before importing it.
