So I'm one of those weirdos who actually keeps a large USB thumbdrive full of music in his car, and often prefers to use it as a source of music playback. I even go so far as to organize the files in the music collection so they're easy to browse. After upgrading to 8.0, I've noticed a few changes that actually make the user experience a whole lot worse. Some feel like outright bugs, and others feel like blatant user interaction oversights. So here goes... When browsing by "Folders", album tracks are sorted alphabetically by song title. This completely ignores the track number in the metadata, and the file name itself (which, in my case, often has a track number prefix.) However, if you browse to the exact same album via the "Albums" grouping, tracks are correctly sorted. They removed the alphabetical jump-list from the right-hand side of the media lists, making it so there's no longer a quick way to skip to a particular letter in the list. Scrolling large lists of media is now extremely sluggish and painful. You can almost feel the system groaning at you as you do it, and it'll even mistake a scroll gesture for a tap gesture amidst the sluggishness. As such, you'll accidentally open albums during the process. When you browse back from an album, it jumps you back to the top of the entire list. Given how painful scrolling that list is, this just makes that experience even worse. So in short... track sorting is screwed up, and the UI is so damn sluggish its painful to use.
